Questions and Answers

During translation, what is the role of mRNA codons?

  • They regulate the processing steps of pre-mRNA.
  • They specify the order of amino acids in a protein from N-terminal to C-terminal. (correct)
  • They determine the genetic DNA sequence.
  • They initiate the process of transcription.

    • How many codons code for amino acids?

  • Multiple, but tend to have four bases.
  • 64
  • 61 (correct)
  • 3

    • What is the function of start codon in mRNA?

  • Regulates the transcription process.
  • Initiates the translation process. (correct)
  • Specifies the end of translation.
  • Codes for a specific amino acid.
