RNA Types and Functions

This video tutorial from Two Minute Classroom explains the roles of different types of RNA: mRNA, tRNA, and rRNA. mRNA acts as a messenger between DNA and protein production, tRNA brings amino acids together during translation, and rRNA is a key component of ribosomes that helps build proteins. The video also highlights the transcription and translation processes, emphasizing how these RNA types contribute to protein synthesis.

What does mRNA stand for?
