mRNA (messenger RNA)

mRNA, or messenger RNA, is a type of genetic material that plays a crucial role in the process of making proteins within cells. It acts as a messenger, carrying instructions from DNA (the genetic blueprint) in the cell's nucleus to the ribosomes, which are the cellular machinery that produce proteins. Once the mRNA reaches the ribosomes, they read its instructions and assemble the building blocks of proteins based on that information. This process is essential for the growth, repair, and functioning of all living organisms. mRNA is also key in many modern medical technologies, including vaccines.
