Do you expect the pI for the sickle-cell β-globin to be higher or lower than the pI for wild-type β-globin? Explain.

The sickle cell  β-globin contains more negative charge than that of wild-type β-globin due to the mutation in HBB gene. The means that it' requires a higher basic level of pH than that of wild-type β-globin to reach it's pI.

So, the sickle cell β-globin has a higher pI than that of wild-type β-globin.

hormones in blood stream

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

yes you are doing it right great gob
