Question

Which of the following is not true about DNA replication?

Select one:
a. The double strand unwinds and unzips while it is being duplicated.
b. The process is catalyzed by enzymes called DNA mutagens.
c. It must occur before a cell can divide.
d. Two complementary strands are duplicated.

Answer 1

DNA replication is catalyzed by enzymes called DNA polymerases, not DNA mutagens.

Step-by-step explanation:

DNA replication is a process that involves unwinding and unzipping the double strand of DNA, synthesizing complementary strands, and releasing the parent and daughter DNA. One of the options listed, option b, states that the process is catalyzed by enzymes called DNA mutagens. However, this statement is not true. DNA replication is catalyzed by enzymes called DNA polymerases, not DNA mutagens. DNA mutagens refer to substances that can cause mutations in DNA, but they do not play a role in DNA replication.
