Question

Organisms must rapidly acclimate to changes in their environment. For instance, temperature changes cause a rapid change in the proteins within nerve cells of the octopus (Octopus bimaculoides) that result in functional changes to proteins such as neurotransmitters and motor proteins. Some of these changes are single amino acid substitutions that are not associated with any mutations in the octopus genome, and also could not be ascribed to changes in transcriptional activation/initiation or splicing. 

A)    Propose a hypothesis for how these protein changes occur. Be certain to detail what type of molecular change(s) occur to which molecule(s)


B)    Suggest a reason why it might be advantageous to the octopus to not make the change at the level of transcriptional activation.
