WebKey points: In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another. WebEukaryotic DNA never leaves the nucleus; instead, it’s transcribed (copied) into RNA molecules, which may then travel out of the nucleus. ... Prokaryotes, which do not have a nucleus, don't have nucleoli and build their ribosomes in the cytosol. ... Eukaryotic ribosomes may be either free, meaning that they are floating around in the ...
