DNA is the source of for
RNA production (transcription) and thus
for protein sis. DNA is still the
basis of due to its replication
capability.

The messenger RNA is the template for
protein synthesis (). In this
process tRNA and rRNA also participate
since the first carries acids for
the polypeptide chain formation and the
second is a structura lconstituent of
(the organelles where
proteins are made).
