Question

DNA replication is said to be semiconservative. This means that ____

A) each new double helix consists of one old and one new strand
B) one strand of the new double helix is made of DNA and the other strand is made of RNA
C) the old double helix is degraded and half of its nucleotides are used in the construction of two new double helices
D) one of the two resulting double helices is made of two old strands, and the other is made of two new strands

Answer 1

DNA replication is semiconservative, meaning that in each new DNA molecule, one strand is newly synthesized while the other is a preserved parental strand, ensuing accurate genetic information transfer.

Step-by-step explanation:

DNA replication is said to be semiconservative. This means that each new double helix consists of one old and one new strand. Specifically, during DNA replication, each strand of the original DNA molecule serves as a template for the synthesis of a new, complementary strand.

As a result, the two resulting DNA molecules each contain one strand from the parental DNA and one newly synthesized strand. This process ensures the genetic information is accurately passed down to the daughter cells.
