Messenger RNA (mRNA)
Messenger RNA contains genetic information. It is a copy of a portion of the DNA.
It carries genetic information from the gene (DNA) out of the nucleus, into the cytoplasm of the cell where it is translated to produce protein.

Messenger RNA (mRNA) is the blueprint for construction of a protein. Ribosomal RNA (rRNA) is the construction site where the protein is made. Transfer RNA (tRNA) is the truck delivering the proper amino acid to the site at the right time.

Messenger RNA (mRNA): Proteins are not synthesized directly from genomic DNA. Instead, an RNA template (a precursor mRNA) is constructed from the sequence of the gene. This RNA is then processed in various ways, including splicing.

The messenger RNA (mRNA), the product of transcription and splicing, carries the code for the order of insertion of amino acids. This genetic code is a triplet code without punctuation.

What is messenger RNA?
The sequences coding for proteins are present in the DNA in the genome, but they first have to be transcribed into RNA in the form of RNA sequences, ...
