Which step begins the process of translation?

A. A ribosome reads the codon sequence at the 5' end of mRNA.

B. The ribosome releases the protein and detaches from the mRNA.

C. A stop codon indicates the end of the polypeptide.

D. tRNA connects an amino acid to the ribosome

The correct answer is A a ribosome reads the codon sequence at the 5" end of mRNA.

Explanation:

Translation is a process of central dogma of molecular biology which deals with the formation of protein molecule from an mRNA molecule in the cytoplasm of eukaryotic cell and in the nucleus of prokaryotic cell.

During the initiation of translation the Ribosome along with its smaller subunit binds to the first codon (AUG) of mRNA and read that codon from the 5" end and after doing this ribosome moves to the next codon.
