Scientists study and track other animals' genes in an effort to understand how non-human creatures' genes work and operate. They do this to understand genetic risk factors in illnesses in the human population. This comes primarily from research on the genes of mice because mice are incredibly genetically close to humans --- there are literally thousands of genes in mice and rats that are phenomenally similar to humans. Manipulating their genes is extremely simple, such as adding or deleting genes to better understand their bodily functions --- also known as genetic engineering. The majority of mice and rats used in genetic research and medical studies are inbred and genetically similar, which makes the medical trial outcomes more consistent. This helps us find an understanding in whatever it is that we're trying to find.
Scientists track the genes of other organisms like rats and mice in databases because these organisms share evolutionary similarities with humans, allowing researchers to study biological processes, diseases, and potential treatments that can apply to humans.
Rat genes are important to human gene research due to their similarities and potential for modeling human diseases and drug responses.
Scientists track the genes of various organisms, including rats and mice, in databases because these organisms serve as valuable model systems for studying biological processes, genetics, diseases, and potential treatments that are relevant to humans. Despite the differences in size and appearance, many biological functions and genetic pathways are conserved across species due to evolutionary relationships.
Rats and mice share a significant portion of their genes with humans and have similar anatomical and physiological characteristics. This similarity allows researchers to study fundamental biological mechanisms and disease processes in these animals and extrapolate the findings to humans. By tracking the genes of these organisms in databases, scientists can access a wealth of information about their genetic makeup, which aids in designing experiments and conducting comparative studies.
Rat genes, in particular, are important to human gene research because rats have a similar genomic organization and share many orthologous genes with humans. Rats are used extensively in medical and scientific research as model organisms to study human diseases such as cancer, cardiovascular disorders, diabetes, neurological conditions, and more. Their genetic and physiological similarities enable researchers to mimic disease processes and test potential therapeutic interventions in rats before moving to human clinical trials.
In summary, tracking the genes of organisms like rats and mice in databases is essential for advancing our understanding of genetics, diseases, and treatments that apply to humans. Rat genes are valuable in human gene research due to their evolutionary relationship with humans and their potential for modeling human diseases and drug responses, ultimately contributing to the development of medical treatments and therapies.

What is the role of reverse transcriptase in DNA technologies?
A. To unzip DNA strands
B. To find mRNA
C. To produce proteins
O D. To make cDNA
Answer:
D...........................................................................
Explanation:
Reverse transcriptase may be a DNA polymerase enzyme that transcribes single-stranded RNA into DNA.
What is reverse transcriptase?
This enzyme is in a position to synthesize a double-stranded DNA into a single-strand DNA once the RNA is transcribed in 1st step. Found in retroviruses, like the human immunodeficiency virus (HIV).Reverse transcriptase is used to form a cDNA copy of the mRNA. The cDNA sample is then amplified by PCR. This yields multiple copies of cDNA without intronsThus, we can conclude that the correct option is D.
To make cDNA is the role of reverse transcriptase in DNA technologies.

Factors that could affect the current oxygen and carbon dioxide levels?
Explanation:
There are many factors, both natural and man-made, that affect the levels of carbon dioxide and oxygen in the atmosphere. Some of them are:
Burning of fossil fuels increases the level of carbon dioxide.
Cleaning agricultural land increases the level of carbon dioxide.
The availability of nutrients in plants affects the synthesis of oxygen.
The intensity of the sunlight can increase or decrease the synthesis of oxygen.
Deforestation and industrial expansion greatly affect carbon dioxide and oxygen levels.
The increase in consumer products due to population explosion and advances in health care can also fluctuate carbon dioxide and oxygen levels.
An increase in oxygen levels is thought to promote healthy living in the environment, whereas a decrease in oxygen levels can lead to a decrease in atmospheric layers (thinning of the ozone layer). This reduction allows more sunlight to reach the Earth's surface. Sunlight gets trapped inside the Earth and raises the temperature of the planet. It is also known as global warming.
A reduction in carbon dioxide to a certain level is good for the environment, but lower than normal levels can affect oxygen synthesis as plants absorb carbon dioxide and use it to synthesize oxygen during photosynthesis. Since carbon dioxide is a greenhouse gas, an increase in its level will cause global warming.

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the ________ period during which no muscle tension is observed while the neurotransmitter is being released by exocytosis, diffusing across the synaptic cleft, and binding to its receptor to activate the muscle cell. relaxation latent contraction refractory
Answer:
Immediately following the arrival of the stimulus at the axon terminal there is a short period called the latent period.
Explanation:
When a stimulus reaches the terminal of an axon, a period known as the latent period begins. This period has a short duration and during it it is possible to observe the blockage of new stimuli in the nerve fiber. Thus, the new stimuli fail to trigger an impulse and no muscle tension to be observed.
While the latent period is not finished, the neurotransmitter is released through the action of exocytosis that moves until it gets access to the receptor capable of activating the muscle cell.

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.
