mRNA is a type of RNA that carries genetic information from the DNA in the nucleus to the cytoplasm, where it serves as a template for protein synthesis.
Think of mRNA like a courier. It takes the message (genetic information) from one place (the DNA in the nucleus) and delivers it to another place (the ribosomes in the cytoplasm), just like a courier would deliver a package.
Transcription: The process by which genetic information is copied from DNA to mRNA.
Codon: A sequence of three nucleotides on an mRNA molecule that corresponds with a specific amino acid or stop signal during protein synthesis.
Translation: The process by which the genetic code carried by mRNA is decoded to produce the specific sequence of amino acids in a polypeptide chain.
