In semiconservative DNA replication, the copying of genetic information is efficient because:
A
Replication proceeds by randomly assembling nucleotides without needing an existing strand, which speeds synthesis.
B
Each original (parental) strand serves as a template for synthesis of a complementary new strand via base-pairing rules.
C
Both parental strands remain together and a completely new double helix is synthesized separately, doubling the DNA without templates.
D
Only one parental strand is copied while the other is degraded, reducing the amount of DNA that must be synthesized.
