What is concept of mRNA?

Answer 1

Messenger RNA id transcribed from the DNA of the nucleus and then, after modification, leaves the nucleus. The mRNA is then threaded through a ribosome where translation takes place. A transfer RNA brings the amino acid that matches the three base codon of the mRNA to the ribosome, as these codons proceed through the ribosome the matching amino acids attach one to the other in a long chain that exists the ribosome as a polypeptide; the primary structure of a protein.

Answer 2

Ok what i gather from you question is what is mRNA and why is it used?

mRNA is a short strand of RNA is a string used in the process of turning DNA into proteins. mRNA is used because is saves the DNA being damaged the the replication process. it is there for called messenger RNA as it is used only to pass on information

mRNA's role in the production of proteins is to pass on the information from the DNA to be translated by tRNA.

If you are asking about "How mRNA fits in within transcription and translation" or "what is transcription and translation" The following site explains all of it. Or if you rephrase you question i will change my answer to what you need

Answer 3

Transcription. {It is accompanied by (pre) mRna splicing in eukaryotes.}
