What role does mRNA plsy in dene expression?

mRNA, or messenger RNA, plays a crucial role in gene expression by serving as the intermediary between DNA and protein synthesis. It is synthesized from a DNA template during transcription, carrying the genetic information needed to produce specific proteins. Once formed, mRNA is translated by ribosomes into amino acid sequences, ultimately determining the structure and function of proteins in a cell. This process is essential for cellular functions and responding to environmental changes.
