What does mRNA stand for?

• A. Messenger RNA
• B. MicroRNA
• C. Mitochondrial RNA
• D. Monocistronic RNA

Answer: (A)

mRNA stands for messenger RNA, the molecule that carries genetic instructions from DNA in the nucleus to the ribosome where proteins are built. The name reflects its role as a message carrier for protein synthesis. Distinct RNA types include microRNA, which helps regulate gene expression rather than serve as a protein-building template; mitochondrial RNA, which comes from the mitochondria and participates in organelle gene expression; and monocistronic RNA, a descriptor used for mRNA that encodes a single polypeptide (unlike polycistronic mRNA in some bacteria).
