Again, look at the table. Examine the saturated thickness levels between 1975 and 1990 and between 1995 and 2010. Each of these are fifteen-year spans, but the decrease in saturated thickness is not the same. Even if the population were to stay the same over this time, why do you think the drop in thickness is not as great?

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.
