Scientists observed a population of monkeys on an island. The monkeys were observed to have different finger lengths. Some monkeys had long fingers, some had short fingers, but the majority of them had finger lengths that were closer to the short finger length. Explain how this trait in the population of monkeys would evolve over time if tree branches on the island grew thicker. Would this be an example of stabilizing, directional, or disruptive selection?

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
