Question

Quizplus · Accepted Answer

The point at which DNA synthesis is initiated is called the origin of replication. It is the specific sequence of nucleotides where DNA replication begins, and it is recognized by the replication machinery as the starting point for DNA synthesis. Choice A (primer) is a short strand of RNA or DNA that serves as a starting point for DNA synthesis, but it is not the point of initiation. Choice B (primase) is an enzyme that synthesizes RNA primers, but it is not the point of initiation. Choice C (start codon) is a sequence of nucleotides in mRNA that signals the start of protein synthesis, not DNA replication. Choice D (replication fork) is the site where the two strands of DNA separate during replication, but it is not the point of initiation.
