#Unit 11. Evolution and Behavior

When the fitness interests of two individuals are different, they are in conflict.

The evolution of cooperation and conflict depends on when these kinds of behaviors are favored by natural selection.

Shortly after transcription initiation, Pol II is paused 30 nucleotides downstream from the initiation site, waiting for the recruitment of the capping enzymes to add the cap to the 5’ end of nascent RNA. Without this protection, nascent RNA may be vulnerable to attack by 5’–3’ exonucleases, and such trimming may induce the Pol II complex to fall off of the DNA template.
