A macromolecule that acts as a matrix in a cell.

This is messenger RNA (mRNA). It is a complex macromolecule that is created on DNA. The role of messenger RNA is to transfer information about the need for the synthesis of a certain protein to the ribosome. Also, mRNA contains information about the structure of a given protein. But these are not strict rules of synthesis, but rather a “recipe for proteins”. That is why messenger RNA is also called messenger RNA. But when translating proteins, tRNAs are also important, which transfer amino acids to the ribosomes and rRNA, which make up the ribosomes of the cell.
