What is True regarding cytoplasmic m RNA? and explain in detail?
mRNA is chiefly transcribed from nuclear DNA
MW of cytoplasmic mRNA is lesser than the heterogenous RNA .
mRNA contain only uracil not the thymine .
Sugar is ribose moiety, not the deoxyribose moiety . Messenger RNA (mRNA) is a molecule of RNA that encodes a chemical "blueprint" for a protein product. mRNA is transcribed from a DNAtemplate, and carries coding information to the sites of protein synthesis, the ribosomes. In the ribosomes, the mRNA is translated into a polymer of amino acids: a protein. (This process is sometimes referred to as the central dogma of molecular biology.) Heterogeneous nuclear RNA (hnRNA) a diverse group of long primary transcripts formed in the eukaryotic nucleus, many of which will be processed to mRNA molecules by splicing.
