Based on the data in Table 1, describe the general relationship between the sensitivity of cells to Sepin‐1 and the concentration of separase in the cells. Use the Figure 1 data to calculate the ratio between the amount of Sepin‐1 required to kill 50% of the cells in the cell line that is most sensitive to the compound and the cell line that is least sensitive to the the compound and the cell line that is least sensitive to the compound.

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.
