Detailed explanation-1: -Definition. Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.
Detailed explanation-2: -Transcription is the first step in gene expression. It involves copying a gene’s DNA sequence to make an RNA molecule.
Detailed explanation-3: -messenger RNA / mRNA mRNA is created during transcription. During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides known as ribonucleic acid, and is single-stranded.
Detailed explanation-4: -Listen to pronunciation. (tran-SKRIP-shun) 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.
Detailed explanation-5: -Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis.
