Full Answer. It serves as a courier between the cytoplasm and the nucleus. Messenger RNA has its own helper, in the form of a molecule called polymerase. This molecule transcribes the codons directly onto the RNA. The mRNA then leaves the nucleus, and ribosome subunits attach themselves to the mRNA to read it off like a ticker tape.

Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. RNA polymerase transcribes primary transcript mRNA (known as pre-mRNA) into processed, mature mRNA. This mature mRNA is then translated into a polymer of amino acids: a protein, as summarized.

BioCoach Activity Concept 10: Pre-mRNA Processing (Splicing) Eukaryotic pre-mRNAs typically include introns. Introns are removed by RNA processing in which the intron is looped out and cut away from the exons by snRNPs, and the exons are spliced together to produce the translatable mRNA.

Capping protects the nascent pre-mRNA against degradation; failure to cap or loss of cap leads to rapid breakdown of the RNA.The m 7 G-cap is bound by two nuclear Cap Binding Proteins, CBP20 and CBP80.Only CBP20 appears to be in direct contact with the cap.

Full Answer. It decides what amino acid is needed by looking at the mRNA. The mRNA molecule has three nucleotides, or codons, that refer to a specific amino acid. Once the tRNA molecule recognizes the particular amino acid it needs, its second function kicks in and it becomes a transferrer, moving that amino acid into the growing chain of amino acids.
