In bacteria, the DNA forms into a long and twisted loop. The contorted tracks... close... to form a singular circular . In eukaryotic cells, there are usually a number of different chromosomes... each has two separate ends.

[I]t's interesting to me that the bacteriophages, the viruses that you find in bacteria, are not remotely similar to the ones that you find infecting archaea, which again are not remotely similar to eukaryotic viruses. ...They're different in their appearance. They're different in their mechanisms in which they force their... I mean the bacteriophages are these classic lunar module landing things... They are stunning things to look at. ...Some es look like bottle balls or postage stamps, strange shapes... They don't have any genes in common.
