Why must an mRNA copy be made for Protein Synthesis?

Question

thanks

Answer 1

The mRNA is a messenger. That's what the "m" stands for. It takes the information found in a gene and copies it. The gene is like the master library of the body. It contains all the information on what proteins need to be made and when. The mRNA is like someone going into the library and making a copy of a page with vital information, and then leaving with that information, and taking it to a factory (the ribosome) where it can actually be used. Once in the ribosome the information, which are the neucleotides copied from the gene, can be translated into the anticodons needed for a particular protein.
