Suppose you were the commissioner of corrections for your state. which correctional activities might come within your domain? which mostly would not

What is the one part of the nucleotide  that differs among the other different nucle  tides?

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
