The role of mRNA in expressing specialized structures is PROVIDING INFORMATION to form proteins. This molecule (mRNA) serves as a nexus between DNA and proteins.
During gene transcription, a fragment of DNA called 'gene', which is localized on a specific site in a chromosome, is used as a template to create a complementary messenger RNA (mRNA) molecule.
Subsequently, this mRNA is in turn used as a template to create a polypeptide chain (i.e., a protein) by a process called translation.
The order of triplets of nucleotides or 'codons' in mRNA indicates how to add specific amino acids in the nascent protein sequence during translation.
Thus, the mRNA molecule serves as a template for the generation of a specific protein sequence.
