What is the process of copying DNA called?

  • A. Transcription
  • B. Translation
  • C. Replication
  • D. Mutation
Correct Answer: C

Rationale: The correct answer is C, Replication. Replication is the process of making an identical copy of DNA. During replication, the DNA double helix unwinds, and each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules. Transcription (choice A) involves the synthesis of mRNA from a DNA template, not the direct copying of DNA. Translation (choice B) is the process of converting mRNA into a sequence of amino acids to form a protein, not copying DNA. Mutation (choice D) refers to changes in the DNA sequence, which can occur during replication but is not the process of copying DNA itself.
