Question

Consider the process that a cell uses to replicate its double-stranded DNA to make copies for daughter cells. Which statement describes the DNA in daughter cells?

A) The double helix in one daughter cell consists of two strands that were originally in the parent cell, while the double helix in the other daughter cell consists of two newly made
strands.
B) The two strands of the double helices in both daughter cells consist of segments of new and parental DNA.
C) The double helices in each daughter cell consist of one parental strand and one newly made strand.

Answer 1

During DNA replication, each strand of the double helix serves as a template for the synthesis of a new complementary strand. The resulting daughter DNA copies have the same sequence as the parent DNA and are divided equally into the two daughter cells.

Step-by-step explanation:

During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied.

The new strand will be complementary to the parental or 'old' strand. When two daughter DNA copies are formed, they have the same sequence and are divided equally into the two daughter cells.
