Ribosomes

      The Ribosomes are made in the nucleus of r-RNA.
      The small 30s and large 50s subunits fit together and translate the m-RNA sequence into protein primary structure.

EPIGENETICS

"The regulation of gene expression (on-off!) through various cellular processes including DNA methylation, histone acetylation, and RNA interference."

The environment may effect gene expression!

    • Fertilization is not the only means for the transfer of genetic information (DNA)
    • 'Horizontal Gene Transfer' link 'vector'
    • Bacteria insert DNA into host organisms w/ plasmid
