Question

Quizplus · Accepted Answer

The site where the old DNA strands separate and new DNA strands will be synthesized is called the replication fork. This is the point where the unwinding of the double-stranded DNA molecule occurs and the two strands separate, creating a Y-shaped structure. The new strands are synthesized in the 5' to 3' direction by DNA polymerase, starting at the replication fork. Therefore, the correct answer is E, replication fork. Primer is a short RNA or DNA segment that initiates DNA synthesis, Okazaki fragments are short segments of DNA synthesized on the lagging strand, template is the original DNA strand that serves as a guide for synthesis of a complementary new strand, and rolling circle is a mechanism of DNA replication used by some viruses and bacteria.
