Messenger RNA (mRNA) is a type of genetic material that plays a crucial role in the process of making proteins in our cells. It is created from DNA, which contains the instructions for building proteins. Once formed, mRNA carries these instructions from the nucleus of the cell to the ribosomes, the cellular machinery that assembles proteins. When mRNA reaches the ribosomes, it serves as a template for assembling amino acids into a specific sequence, ultimately forming a protein. This process is essential for various functions in the body, including growth, repair, and maintaining overall health. mRNA is also the basis for some vaccines, like those for COVID-19.
