Jill is doing an experiment on the movement of pill bugs. She will place the pill bugs on flat surfaces covered with
different materials to see how the texture of each material
affects the bugs' movement.
How can Jill use her imagination in this experiment?

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.
