Detailed explanation-1: -The mRNA is then pulled through the ribosome; as its codons encounter the ribosome’s active site, the mRNA nucleotide sequence is translated into an amino acid sequence using the tRNAs as adaptors to add each amino acid in the correct sequence to the end of the growing polypeptide chain.

Detailed explanation-2: -translation – the process in which a cell converts genetic information carried in an mRNA molecule into a protein.

Detailed explanation-3: -A ribosome converts mRNA into a protein. A ribosome is an organelle that is found within the cell of an organism. The job of this organelle is to take the mRNA, or the code that comes from the transcription phase (i.e., the process of copying DNA), and form a peptide chain according to what the code describes.

Detailed explanation-4: -Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
