Ribonucleic acid, or RNA, is a molecule with a structure very similar to DNA. The most important structural difference is that it is single chain, instead of double chain cone DNA and also that the base uracil has replaced thymine, that is, the C-T pairing of the DNA will be C-U in the RNA. At a functional level, RNA is synthesized and degraded according to the needs of the cell to perform various functions. ThemRNAis the messenger that is obtained from the transcription of the genes and that will be translated into protein.rRNAis part of ribosomes. The tRNAs are responsible for associating the amino acids to the triplets of themRNA. ThemicroRNAsandsiRNAare related to the regulation of gene expression.
