Questions and Answers

What is the role of tRNA in protein synthesis?

  • Initiates DNA replication
  • Carries amino acids to the ribosome (correct)
  • Transcribes DNA to RNA
  • Forms the ribosome structure

    • How does a point mutation differ from an insertion mutation in DNA?

  • Point mutation involves multiple nucleotide changes, while insertion mutation changes only one nucleotide.
  • Point mutation and insertion mutation have no significant difference.
  • Point mutation substitutes one nucleotide with another, while insertion mutation adds an extra nucleotide. (correct)
  • Point mutation deletes a nucleotide, while insertion mutation rearranges the nucleotides.
