What it means
A molecule made of one strand of building blocks called nucleotides. Messenger RNA (mRNA) copies a gene from DNAdee-en-AY (said as letters)Deoxyribonucleic acid: the molecule in cells that carries the genetic instructions for growth and function.Full entry and carries it to the ribosomes, where the cell reads it to build a protein. Some viruses, such as influenza, HIV and the virus that causes COVID-19, carry their genes as RNA instead of DNA. mRNA vaccines give cells instructions to make a harmless piece of a virus, so the immune system learns to recognize it.
