What is the role of mRNA in protein synthesis?

mRNA serves as the messenger that carries the genetic instructions from DNA to the ribosome, where proteins are built. It is created by transcription in the nucleus using DNA as a template, then exits to the cytoplasm. There, the ribosome reads the mRNA in codons (groups of three bases) and uses that information to assemble the corresponding sequence of amino acids, with tRNA delivering each amino acid corresponding to each codon. mRNA itself does not become protein and does not perform chemical reactions to link amino acids; that catalytic work is done by the ribosome’s rRNA. So the mRNA’s essential role is to deliver the genetic code from DNA to the ribosome to guide protein synthesis.
