In a presentation to the Linnean Society of London in November
1831, the Scottish botanist Robert Brown (perhaps better known for
his discovery of Brownian motion) mentioned almost as an
afterthought that in orchid epidermal cells, a single "circular
areola" could be seen, a "nucleus of the cell as perhaps it might
be termed." Thus, the term "nucleus" (from Latin nucleus or
nuculeus, "little nut" or kernel) was born for the compartment of
the eukaryotic cell that contains the maj- ity of genetic
information. One hundred and seventy-seven years later, we know
that the nucleus is the site where genetic information is stored in
the form of DNA, and where it is protected from damage, duplicated,
divided, recombined, repaired, and "expressed." For the latter, the
genetic information is faithfully transcribed from DNA to RNA, then
released from the nucleus into the surrounding cytoplasm. Most
likely translated into polypeptide chains, the information
re-enters the nucleus in the form of diverse proteins that function
in the processes listed above.
