Read the passage and answer the following questions :
Translation refers to the process of polymerisation of amino acids to form a polypeptide. The order and sequence of amino acids are defined by the sequence of bases in the mRNA. The amino acids are joined by a bond which is known as a peptide bond. Formation of a peptide bond requires energy.
At which codon the ribosome binds to the mRNA to initiate translation ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) -AUG
The codon at which the ribosome binds to the mRNA to initiate translation is AUG.
AUG is the start codon and also codes for the amino acid methionine. It serves as the signal for the beginning of the protein synthesis process during translation. The initiator tRNA molecule, carrying the amino acid methionine, recognizes and binds to the AUG start codon on the mRNA. This initiation codon is where the ribosome begins the translation process, assembling the protein based on the genetic information encoded in the mRNA.
