What does messenger RNA do during protein synthesis?

Question

Messenger RNA or mRNA, is created in the nucleus using DNA as a template. mRNA is single-stranded whereas DNA is double-stranded, and mRNA has uracil instead of thymine as one of its bases. Otherwise mRNA is an exact copy of DNA and contains all the same genetic information.

What Is The Role Of Messenger RNA

The role of mRNA is to take the genetic information outside the nucleus so that protein synthesis can occur. During protein synthesis mRNA serves as the information port that tells ribosomes what proteins to produce. The ribosomes ‘read’ the genetic information contained within the mRNA, and they then send tRNA to bring back the individual amino acids needed to build that protein. Once the pieces are in place, the protein can be assembled and sent wherever it needs to be. Basically, mRNA’s role is to make protein synthesis possible by providing the protein blueprints.
