Question
DNA replication ________. a. can also be called mitosis b. is spontaneous, not requiring enzyme action c. takes place during interphase of the cell cycle d. occurs only in translationally active areas e. requires uracil
Solution
The correct answer is c. DNA replication takes place during interphase of the cell cycle.
Here's why:
a. DNA replication is not the same as mitosis. Mitosis is the process of cell division, while DNA replication is the process by which a DNA molecule is copied.
b. DNA replication is not spontaneous and does require the action of several enzymes, including DNA polymerase.
c. This is correct. DNA replication occurs during the S phase of interphase in the cell cycle, before the cell enters mitosis or meiosis.
d. DNA replication is not limited to translationally active areas. It occurs in the nucleus of the cell, where the DNA is located.
e. Uracil is not required for DNA replication. Uracil is a nucleotide base found in RNA, not DNA. In DNA, the base thymine is used instead.
