Which Description Of Dna Replication Is Correct?

( Concept 16.2) Ligase assembles single-stranded codons, then polymerase knits these codons together into a DNA strand. The two strands of DNA separate, and restriction enzymes cut up one strand. Then, the DNA polymerase synthesizes two new strands out of the old ones. Helicases separate the two strands of the double helix, and DNA polymerases then construct two new strands using each of the original strands as templates. The two strands separate, and each one receives a complementary strand of RNA. Then this RNA serves as a template for the assembly of many new strands of DNA. Ligase separates the two strands of the DNA double helix. Then, DNA polymerase synthesizes the leading strand and primase synthesizes the lagging strand.

Helicases separate the two strands of the double helix, and DNA polymerases then construct two new strands using each of the original strands as templates. Correct. In the semiconservative model of DNA replication, the two strands of the parental molecule separate, and each functions as a template for the synthesis of a new complementary strand.
