DNA Replication: Mechanisms and Enzymes · Zoology

Which specific region of the DNA serves as the starting point for replication?

  1. Promoter (transcription start site)
  2. Origin of Replication (OriC)
  3. Terminator (replication stop site)
  4. Operator (repressor binding site)
Show answer and explanation

Correct answer: Origin of Replication (OriC)

Replication begins at a defined DNA sequence called the origin of replication. Prokaryotes like E. coli have a single OriC, while eukaryotic chromosomes have thousands of origins to enable rapid, parallel replication.
