Messenger RNA (mRNA) | Description & Function | Britannica
WEB1 day ago · messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). The molecule that would eventually become known as mRNA was first described in 1956 by scientists Elliot Volkin and Lazarus Astrachan.
Messenger RNA - Wikipedia
WEBRNA polymerase transcribes a DNA strand to form mRNA. The brief existence of an mRNA molecule begins with transcription, and ultimately ends in degradation. During its life, an mRNA molecule may also be processed, edited, and transported prior to translation.
