#Unit 2. Cellular Organization

Hydrolysis of the bound GTP accompanies disassembly of the SRP and SRP receptor and initiates transfer of the nascent chain and ribosome to a site on the ER membrane, where translocation can take place.

#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.
