DNA Replication

APBIO-JOYXBB

Replication of DNA is a semiconservative process.

Which of the following BEST describes this characteristic of replication?

A

Each new DNA molecule is made of pieces of the parent strand alternating with segments that have been newly constructed from free nucleotides.

B

One strand of the DNA molecule acts a template for transcription, in which a strand of mRNA is formed.

C

The double-stranded DNA molecule unzips, acts as a template for a new DNA molecule to be constructed, and then zips back together into its original form.

D

Each strand of the original, double-stranded DNA molecule serves as a template for a newly constructed, complementary strand.
