GENES IN ACTION


A gene can be defined as a sequence of bases in DNA that codes for
the synthesis of one polypeptide, and genes must somehow transmit
their information from the nucleus to the cytoplasm, where
protein synthesis occurs. The synthesis of an RNA molecule from
DNA is called transcription (L. trans, across scriba, to write),
and the formation of a protein from RNA at the ribosome is called
translation (L. trans, to transfer latere, to remain hidden).
