Answer: Option B) The fidelity of DNA synthesis.
Explanation:
In DNA synthesis, some enzymes known as DNA polymerases, catalyze the addition of nucleotides to elongate the already formed DNA chain.
Then, 3'-5' exonuclease activity of DNA polymerase is introduced for proofreading i.e to remove wrongly paired nucleotides from the 3' end of the DNA chain.
Thus, 3'-5' exonuclease activity of DNA polymerase is critical for fidelity of DNA synthesis.
Answer:
Explanation:
There are many characteristics of life, including, <u>cells.</u> A cell is a tiny unit of life that carries out many different processes.
If something is considered living, it must have at least one cell, but it can have more. For example, bacteria is unicellular and living. We (humans) are also living, but made of billions of cells.
Therefore, for something to be considered living, it must be composed of at least one <u>cell. </u>
The correct answer is the loss of genetic variation. This is because after genetic drift, the original poulation of a species decreases in number, and the new dominant genes in the population will live up to reproductive age, and increase the newer genes will thrive.
