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
One double helix in 1 daughter cell consists of 2 strands that were both from parental cells 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 consists 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

In DNA replication, each daughter cell receives a DNA double helix comprised of one parental strand and one newly synthesized strand, following the semiconservative replication model.

Step-by-step explanation:

The process by which a cell replicates its double-stranded DNA is intricate and well-orchestrated. In DNA replication, semiconservative replication is the model brought to light by Watson and Crick. According to this model, the double helix of DNA unwinds and each strand serves as a template for the creation of a new complementary strand.

Therefore, within each daughter cell, the DNA consists of one parental strand and one newly synthesized strand. To reiterate, the double helices in each daughter cell consist of one parental strand and one newly made strand.
