By formation of proteins using the genetic information of mRNA.
Explanation:
Translation is the process of protein synthesis that forms new proteins using the base sequence of mRNA as template. Since mRNA is formed by copying the base sequence of template DNA strand, mRNA serves as carrier of genetic information from DNA to proteins. The newly formed mRNA enter the cytoplasm and joins ribosomes to initiate the process of translation.
