<span>Messenger RNA (mRNA) is known
to be molecules that carries codes (DNA) in the nucleus to the cytoplasm the
sites of protein synthesis. Thus, it is the RNA copy from one section of the
DNA that usually correspond to a single
gene. </span>
Guanine and adenine, structure-wise, are purines.
As we know, vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body, which is a training for your body so if a real antigen attacks it, it will be trained and kill it with ease.
