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. They don't have mechanisms of entry into cells in common. They appear to be independently derived.

The s were acquired by a eukaryotic cell that was already a fully fledged eukaryotic cell.

The sequence of letters in a specifies the sequence of s in a protein. If the sequence of letters is changed—a ''—this may change the structure of the protein (...not always, there is some redundancy... technically degeneracy..—several combinations... can code for the same amino acid.)
