Once Replication in a DNA Molecule is Complete, Each New

Question

Once replication in a DNA molecule is complete, each new DNA molecule contains
A)one old strand and one new strand.
B)the paired old strands and the paired new strands.
C)new DNA polymerase.
D)a new sequence of nucleotides.

Accepted Answer

During DNA replication, the parent DNA strand serves as a template for the synthesis of a new daughter strand. Each new DNA molecule contains one old (parent) strand and one new (daughter) strand. This is also known as semi-conservative replication. Therefore, choice A is the correct answer.
