Answer: It proposes that the entire double‑stranded DNA molecule serves as a template for a whole new molecule of DNA.
Explanation:
In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand serves as template, and then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand for both
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent double strand is retained in the newly synthesized DNA, this model is described as semi-conservative
The conditions exhibited revolve around the plight of the African American family.... the lack of opportunity, the dream of something better, the disappointments of the past, and a fear of the future.
