Detailed explanation-1: -In biology, the process by which a cell makes an RNA copy of a piece of DNA. This RNA copy, called messenger RNA (mRNA), carries the genetic information needed to make proteins in a cell. It carries the information from the DNA in the nucleus of the cell to the cytoplasm, where proteins are made.
Detailed explanation-2: -Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template. Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors.
Detailed explanation-3: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
Detailed explanation-4: -The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.
