mRNA, or messenger RNA, is a type of RNA that is transcribed from DNA and serves as a template for protein synthesis in the cell. It carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are produced. The process begins with transcription, where a specific segment of DNA is copied into mRNA. This mRNA strand then undergoes processing, including splicing and the addition of a 5′ cap and poly-A tail, before it is translated into a protein by ribosomes through the process of translation. Each group of three nucleotides in the mRNA, called codons, corresponds to a specific amino acid, which are the building blocks of proteins. mRNA is crucial for gene expression and plays a fundamental role in the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.
