Which is True About DNA Replication

Question

Which is true about DNA replication?
A) It is semiconservative.
B) It starts at an origin of replication.
C) It is bidirectional.
D) It requires RNA primers.
E) All of the choices are correct.

Accepted Answer

All of the choices are correct. DNA replication is semiconservative, meaning each newly synthesized double-stranded DNA molecule consists of one parent strand and one newly synthesized daughter strand. It starts at an origin of replication, usually a specific sequence of nucleotides in the DNA. Replication is bidirectional, meaning that DNA synthesis occurs in both directions from the origin. RNA primers are required to initiate DNA synthesis by DNA polymerase.
