Describe the role of mRNA in the protein synthesis in a cell.

mRNA caries genetic information in form of nitrogenous bases from chromosomal DNA in the nucleus to the ribosomal RNA in the in the cytoplasm. It acts as a template for protein synthesis. It has complementary DNA base sequence to part of DNA from which it is transcribed.  As a result, mRNA directs the synthesis of proteins as directed by the base sequence on the segment of DNA from it is copied, a process called translation
