Question

In bacteria, the methionine that initiates the formation of a polypeptide chain differs from subsequently added methionines in that _______. view available hint(s) in bacteria, the methionine that initiates the formation of a polypeptide chain differs from subsequently added methionines in that _______. a formyl group is attached to the initiating methionine the initiating methionine is not an amino acid incorporation of the initial methionine does not require a trna its trna anticodon is not complementary to the aug codon

Answer 1

The correct answer is a formyl group is attached to the initiating methionine.

N-Formylmethionine (fMet) is an initiating methionine (a derivative of the methionine) in which a formyl group has been added to the amino group. Besides, bacteria, this amino acid is used in the synthesis of protein(translation) in mitochondria and plastids.
