Translocation on $mRNA$ occurs in the $3' \rightarrow 5'$ direction.

Vedclass · Answer

(D) During protein synthesis,the elongation phase involves the following steps:$1$. The first aminoacyl-$tRNA$ (initiator $tRNA$) carrying methionine binds to the '$P$'-site of the ribosome.$2$. Subsequent charged $tRNA$ molecules,carrying specific amino acids,enter the ribosome at the '$A$'-site.$3$. $A$ peptide bond is formed between the amino acid at the '$P$'-site and the amino acid at the '$A$'-site,a reaction catalysed by the $23S$ rRNA (ribozyme).$4$. Translocation is the movement of the ribosome along the $mRNA$ in the $5' \rightarrow 3'$ direction,not $3' \rightarrow 5'$. Therefore,statement $D$ is incorrect.

Which of the following statements is $INCORRECT$ for the elongation of the polypeptide chain during protein synthesis?
