The image below shows one of the earliest stages of DNA replication. What
role does helicase play in DNA replication?
A. Helicase breaks the hydrogen bonds and unwinds a section of DNA.
B. Helicase connects the floating nucleotides to the template strands.
C. Helicase checks the base pairs in each new strand of DNA.
D. Helicase bonds together pieces of DNA as new strands form.
Answer:DNA helicases are also called molecular motors. They unwind the DNA with the help of ATP hydrolysis, and thus facilitate the replication and transcription processes. ... Studies have suggested that DNA helicases may play a role in plant DNA recombination, as it is prominent during the meiotic prophase of plants.
Explanation:
Role played by Helicase in DNA Replication is to break down the hydrogen bonds and unwinds a section of DNA.
What is DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
What is DNA Replication?In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
DNA replication occurs in all living organisms acting as the most essential part for biological inheritance and it is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.
The cell possesses the distinctive property of division, which makes replication of DNA essential.
DNA is made up of a double helix of two complementary strands. The double helix describes the appearance of a double-stranded DNA which is composed of two linear strands running opposite to each other and twist together to form.
During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.
As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand.
Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
What is the role of Helicases in DNA Replication?Helicases are enzymes that bind and remodel nucleic acid or nucleic acid protein complexes.
Helicases are of two types- DNA Helicases and RNA Helicases.
Role of Helicases:
- Separate the double stranded DNA into single one to allow copying.
- Initiate synthesis at the origin of unwinding
- Helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells, to break the bonds.
- DNA helicases also function in other cellular processes where double-stranded DNA must be separated, including DNA repair and transcription.
- RNA helicases are involved in shaping the form of RNA molecules, during all processes involving RNA, such as transcription, splicing, and translation.

describes the study of microbes in their natural habitats and the relationships between the microbes and that habitat.
Answer:
The study of microbes in their natural habitat and their relationship with each other and their environment is termed as Microbial ecology. It mainly constitutes of Viruses, Eukaryotes ,Bacteria and Archaea as its living entities.
Being omnipresent in the biosphere they impact the other life-forms up to a significant extent.
They also help maintaining biogeochemical cycle by nitrogen fixation, sulfur metabolism and methane metabolism. Microbes also play a vital role of availing energy in the ecosystems where sunlight is scarce and hence photosynthesis is not good means of energy trapping, in such ecosystems the microbes actively engage in fundamental ecological processes including production, decomposition, and fixation inside the host organism.

Formation of an RNA hairpin cannot be the sole factor in the termination of transcription in prokaryotes. Explain why.
Answer:
As the transcription process proceeds, a variety of secondary structures forms by the nascent RNA. t takes place due to the fact that portions of the transcript as complementary base pairs form.
The transcript could be pause but terminate, the hairpin loop causes RNA Pol to pause. There are two different ways to terminate transcription in prokaryotes
- intrinsic termination: in this no external factors required
- Rho protein termination: binds to end of msg and moves along by ATP hydrolysis to catch up (rho is faster)

After nervous stimulation stops, calcium ions returning to the sarcoplasmic reticulum prevent ACh in the synaptic cleft from continuing to stimulate contraction True False
Answer:
False.
Explanation:
Neurotransmitter release occurs from the nervous terminal or varicosities in the neuronal axon. When an action potential reaches the nervous terminal, the neurotransmitter is released by exocytose. The molecule binds to its receptor in the postsynaptic neuron, triggering an answer. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic response. To stop this process the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
• Enzymatic degradation/deactivation: There are specific enzymes in the synaptic space, which are in charge of inactivating the neurotransmitter by breaking or degrading it. The enzyme acetylcholinesterase prevents ACh from continuing to stimulate contraction.
• Reuptake: Receptors located in the presynaptic membrane can capture de molecule to store it back in new vesicles for posterior use. These transporters are active transport proteins that easily recognize the neurotransmitter.

Why has the number of people in the world increased if the human population growth rate has decreased?
Answer:
Life expectancy has steadily risen.
People live longer lives.
To understand the reasons why the number of people in the world has increased and the population growth rate has decreased, it is necessary to understand how the world's demographic growth rate is calculated.
The calculation is made from the balance between the total number of people alive and the total number of deaths that occurred in a period of time.
Therefore, we can understand that the population growth rate has decreased due to several relevant factors, such as:
Increased life expectancy.The decrease in infant mortality.Rising fertility rates.Urbanization.Economic development.These are some of the reasons that help us understand why population numbers increase and population growth rate decreases.
Economic development, new technologies and a better quality of life for the population are directly related to the decrease in the population growth rate.

on which surfaces did you move the box?
Answer:
The force of friction between the two surfaces will increase if the two surfaces are pressed harder against each other. Heavy box will press the floor surface harder as compared to the lighter box. That means the force of friction will be more between the heavier box and surface than between the lighter box and surface. Thus, larger force will be needed to push the heavier box than to push the lighter one.

Hantavirus is a relatively rare emerging infectious disease that is spread by contact with the contaminated feces and urine of rodents, such as deer mice. It does not spread between people and causes flu-like symptoms. How would scientists most likely recommend that the disease be controlled?
Answer:
They would instead focus on controlling and diminishing the rodent population.
Explanation:
They would instead focus on controlling and diminishing the rodent population. The best solutions are always those that target the cause of the problem. Therefore, since the cause of the virus are rodents and that is how the virus spreads, then targetting the rodent population would be the best choice. The scientists would have to figure out a way of keeping track and controlling where the rodent population moves, as well as figuring out how to control their reproduction and diminish their population size. All of this while also trying to predict the possible effects that the population size can have on the environment.

The inferior region of the brain stem, the __________ houses many vital autonomic centers involved in the control of heart rate, respiratory rhythm, and blood pressure.
Answer:
The inferior region of the brain stem, the medulla oblongota houses many vital autonomic centers involved in the control of heart rate, respiratory rhythm, and blood pressure.
Explanation:
The medulla oblongata is the part of the brain that joins the spinal cord and forms the lower part of the brain stem. In the bulb there are ascending (sensory) and descending (motor) fascicles that communicate the spinal cord with the brain, in addition to numerous nuclei or centers (masses of gray matter) that regulate various vital functions. The medulla oblongata has the function of controlling vital and unconscious elements such as the heartbeat and blood pressure. Thus, it is responsible for maintaining the heart rate and regulating vasoconstriction. Also, it manages the control of respiratory function, maintaining it at all times.

When a muscle relaxes: Question 10 options: crossbridges form and muscle extensibility returns the muscle to rest length. crossbridges form and muscle elasticity returns the muscle to rest length. crossbridges stop forming and muscle elasticity returns the muscle to rest length. crossbridges stop forming and muscle extensibility returns the muscle to rest length
Answer:
When a muscle relaxes,
crossbridges stop forming and muscle elasticity returns the muscle to rest length.
Explanation:
Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation will also occur when ATP is no longer available.

A patient with osteoporosis (reduced bone mass) may have a history of health issues. One issue could be
not enough skin exposure to the sun to make Vitamin D.
weak ligaments.
an increase in the absorption of calcium in the digestive system.
weak tendons.
Answer:
not enough skin exposure to the sun to make Vitamin D.
Explanation:
The correct answer would be not enough skin exposure to the sun to make Vitamin D.
The body makes vitamin D by being exposed to the sun and this vitamin and its metabolite are quite important in the homeostasis of calcium. Calcium on its own is very essential to the formation of bones in the body.
Hence, when the skin is not adequately exposed to the sun, the body becomes short of vitamin D and this disrupts the homeostasis of calcium and the formation of bones in the body. Thus, osteoporosis, also known as weak bones, may result.
Answer:
(A) not enough skin exposure to the sun to make Vitamin D.
