Translation

AP Biology· difficulty 2/5

Transfer RNA (tRNA) functions to

  • A

    Recognize stop codons during translation; its release factor triggers polypeptide release

  • B

    Bring specific amino acids to ribosomes; its anticodon base-pairs with mRNA codons

    check_circle
  • C

    Catalyze peptide bond formation at ribosomes; its active site joins adjacent amino acids

  • D

    Carry the genetic code from DNA to ribosomes; its codons base-pair with tRNA anticodons

Explanation

Each tRNA has an anticodon and a 3' end that holds the cognate amino acid (charged by aminoacyl-tRNA synthetase).
