What is the role of enzymes in the DNA replication process?
A. Enzymes read the DNA code and build a new DNA molecule from scratch.
B. Enzymes link together to form a template for a new DNA molecule to be built.
C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
D. Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
Answer: C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
Explanation: This would be known as the double helix because it is being split.
Different enzymes are involved in DNA replication: DNA polimerase, primase, helicase, ligase, and topoisomerase. The correct option is C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
---------------------------------------------
DNA Replication starts in some specific place named replication origin.
Helicase
This is the first enzyme that works in the replication origin. It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA. It breaks hydrogen bonds between nitrogenated bases pairs.Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.
DNA polymerase III
This enzyme is responsible for DNA elongation. It is in charge of adding nucleotides to the growing chain, from 3' to 5' extremes. It includes only nucleotides that complement the original strand. They need to recognize a primer to begin.Primase is in charge of synthesizing primers.
DNA polymerase I eliminate ARN primers and substitute them with DNA.
DNA ligase seals the gaps that remain after replacing the primers.

The diagram shows molecules that a mitochondrion and produces during a cellular process. Which other molecules is a product of this process?
A. DNA
B. RNA
C. C6H1206 (glucose)
D. ATP
Answer:D
Explanation: DNA and RNA are held in the nucleus and have nothing to do with what is shown in the image which is the process of cellular respiration. What is fascinating is that the mitochondrion has its own DNA but it does not produce it in a cellular process. C is false because the mitochondrion takes in glucose so it will go alongside the pyruvate O2. So we can conclude that it produces ATP with H2O and CO2 during this process.
ATP molecule is also a product of the cellular process that occurs in the mitochondria.
MITOCHONDRIA:
The mitochondrion is a membrane bound organelle found in eukaryotic cells. The mitochondrion is regarded as the power house of a cell because it is the site of the cellular process that synthesizes energy for the cell.The cellular process that occurs in the mitochondria is called cellular respiration. Generally, cellular respiration breaks down glucose molecule in the presence of oxygen. The chemical equation is as follows:C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + ATP (energy)
From the attached image, it can be seen that water (H20) and carbon dioxide (CO2) are products. However, ATP molecules is also synthesized during this cellular process. Therefore, ATP molecule is also a product of the cellular process that occurs in the mitochondria.Learn more: https://brainly.com/question/23126016?referrer=searchResults

Can be specialized for specific tasks in multicellular organisms Contain DNA Contain nuclei Are surrounded by a cell membrane Were the first photosynthetic organisms on Earth Can be specialized for specific tasks in multicellular organisms
Answer:
See the answer below
Explanation:
Prokaryotic cell: contain DNA, are surrounded by a cell membrane, were the first photosynthetic organisms on earth.
Eukaryotic cells: can be specialized for specific tasks in multicellular organisms, contain DNA, contain Nuclei, are surrounded by a cell membrane.
Prokaryotic cells are the earliest cells to be formed in the pre-oxygen earth. The photosynthetic prokaryotic cells released oxygen into the atmosphere during the process of photosynthesis and as such, other forms of cells were able to evolve. Prokaryotic cells lack a nucleus and membrane-bound organelles. Their DNA lies freely within the cytoplasm but the cell itself is surrounded by a cell membrane that controls the movement of substances in and out of the cell.
The eukaryotic cells evolved much later after the prokaryotic cell. It has both nucleus and membrane-bound organelles. The DNA is located in the nucleus and the cell is also surrounded by the cell membrane. The eukaryotic cells can aggregate together to form tissues, organs, or systems for a specific task in multicellular organisms.
Answer:
Prokaryotes.
1. Have dna.
2. Were the first photosynthetic organisms on Earth
Eukaryotes.
1. Have DNA
2. Have nuclei.
3. Are surrounded by cell membrane.
4. Can be specialized for specific tasks in multicellular organisms.
Explanation:
Prokaryotes are majorly unicellular organisms that have no membrane bound nucleus or organelles. They are the first photosynthetic organisms on Earth. They lack mitochondria and endoplasmic recticulum.
Eukaryotes are multicellular organisms that have membrane bound nucleus or organelles. They lack chloroplast and they gave mitochondria and Endoplasmic recticulum.

If the strand of DNA being used is A A A T A A G C G C C A, what is the messenger RNA strand that will be produced?
Answer: UUUAUUCGCGGU
Explanation: Remember the base pairing rules: cytosine with guanine and adenine with uracil. To compliment the given strand, you'd have to choose the base that would pair with each individual nucleotide. Since mRNA has no thymine, the adenine must pair with uracil instead. However, it does have adenine to pair with the thymine, even if it doesn't have any of its own.

What is a rule for making a neutral atom which has no charge?
The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).
Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.
There are three conditions possible:
The neutral atom that has no charge - The number of electrons and protons must be the same.E = P
A positive ion that has a positive charge - The number of protons has to be more than the number of electrons.E < P
A negative ion that has a negative charge - The number of electrons has to be more than the number of protons.E > P
Thus, the correct answer is - Electron (E) = Proton (Protons).

White blood cells are especially active when you are sick because their primary job is to fight off infections – often bacteria or viruses that do not belong in you. Once they locate the invader making you sick, they eat it and destroy it. What organelle do you think is plentiful in white blood cells?
Answer:
Lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).

Cell membrane - Controls the passage of materials into and out of a cell
Flagella - Acts as a whipping propeller, moving a cell through its environment
Lysosomes - Digest foreign substances and worn out cell parts
Mitochondria - Produce energy (ATP)
Ribosomes - Makes proteins
Cilia - Structures shaped like small oars that beat in unison to move the cell or the liquid around it
Nucleus - Protects DNA and is considered the “brain” of the cell
Golgi Apparatus - Modifies and packages proteins
Explanation:
The cell membrane separates the inside of the cell from the external environment, and regulates substances that enter and leave the cell.
The nucleus contains the genetic material of the cell, and therefore controls all cellular activities. It is also the site of transcription of mRNAs. mRNAs are translated at ribosomes.
The ribosomes are like factories that synthesize proteins through the process of translation.
When proteins have been produced, they are modified, packaged, and transported to their specific sites by the Golgi apparatus.
Mitochondria are energy-producing organelles - the site of cellular respiration.
Lysosomes are membrane-bound sacsin which waste products are digested
Some cells have cilia, which are hair like-structures that beat in unison to aid in locomotion. Another locomotory organelle is the flagella, which is a whip-like structure that helps some single-celled organelles to move.
