Questions and Answers

What is the Central Dogma of Molecular Biology?

  • The process of DNA replication and transcription in the cell.
  • The theory describing the relationship between nucleic acids and proteins as the flow of information. (correct)
  • The process by which DNA is copied to mRNA for protein synthesis.
  • The mechanism by which RNA directs the translation of proteins.

    • During DNA replication, what is the function of anti-parallel strands?

  • They signal the termination of DNA synthesis.
  • They ensure accurate base pairing between template and complementary strands.
  • They help maintain the stability and structure of the DNA molecule. (correct)
  • They facilitate the binding of free nucleotides during elongation.

    • In transcription, what is the role of tRNA?

  • Direct the translation of mRNA into proteins.
  • Carry amino acids to the correct spot along the mRNA molecule. (correct)
  • Expose the DNA template strand for RNA polymerase binding.
  • Signal the end of the gene sequence.

    • What is the function of ribosomal RNA (rRNA) in protein synthesis?
