Which of the Following Statements About the Newly Synthesized Strand

Question

Which of the following statements about the newly synthesized strand of a human chromosome is TRUE?
A)It was synthesized from a single origin solely by continuous DNA synthesis.
B)It was synthesized from a single origin by a mixture of continuous and discontinuous DNA synthesis.
C)It was synthesized from multiple origins solely by discontinuous DNA synthesis.
D)It was synthesized from multiple origins by a mixture of continuous and discontinuous DNA synthesis.

Accepted Answer

In humans, DNA replication occurs at multiple origins along the chromosome due to the large size of the genome. The replication process involves both continuous (leading strand synthesis) and discontinuous (lagging strand synthesis, which forms Okazaki fragments) DNA synthesis.
