In a eukaryotic cell , DNA in the nucleus programs protein production in the
cytoplasm by dictating the synthesis of messenger RNA ( mRNA ) , which travels
to the cytoplasm and binds to ribosomes . As a ribosome ( greatly enlarged in this

The mRNA molecule then interacts with the cell's protein - synthesizing
machinery to direct the production of a polypeptide . We can summarize the flow
of genetic information as DNA → RNA – protein ( see Figure 5.25 ) . The actual
sites of ...
