Answer:
the making of a polypeptide with a specified order of amino acids using an RNA molecule to provide the sequence information
Explanation:
<u>Translation is the making of polypeptide with a specified order of amino acids using a RNA molecule to provide the sequence information.</u>
In order word, translation is the process of synthesizing protein from mRNA synthesized from DNA template.
<em>During the process of gene expression, the information in the DNA are first transcribed into a mRNA in the nucleus. Thereafter, the mRNA is transported out of the nucleus to the cytoplasm where the genetic codes present in it are translated into their respective amino acids and become linked together through a peptide bond.</em>
Each polypeptide formed has a specific amino acids which correspond to the codons on the mRNA.
