Ribonucleic acid which is needed to convert DNA information into polypeptide sequences. In some viruses RNA serves as the primary database with no DNA involvement certain RNAs have catalytic ability similar to that of protein enzymes , these are called ri bozymes.
RNA perform several function:
MRNA: it specifices the sequence of amino acid in the protein synthesis.
RRNA: it is found in combination with protein and is associated with the structure and function of ribosomes the factories of protein systhesis.
TRNA: it delivers amino acid to ribosomes for protein synthesis.
RNA: as ribonucleo protein participate in the post transcriptional and modification of other RNA.
It is the genetic material carrying hereditary information in many virus.
