A cell utilizes mRNA during transcription and translation. These two processes allow the body to translate DNA into RNA in order to control protein expression and gene expression.
Transcription and translation occur at the cellular level. They both allow genes to be expressed and allow the genetic information held in DNA to be translated by the body. To initiate the process, RNA polymerase II attaches to DNA and creates a pre-mRNA strand. This strand is then processed into a strand of single-stranded mRNA. The mRNA is then translated into a polypeptide chain with the help of a ribosome. The polypeptide strand can be utilized by the body to turn on and off genes.
