Re: Anatomy & Physiology B/C

Ha, Heredity!|When the mother is Rh- & the child is Rh+, the Rh antigens produced by the mother may cross the placenta. When the second fetus is also Rh+, the antigens are already formed, so they are much more likely to attack the fetus (risk increases with successive children). Exactly! Also would...

Re: Anatomy & Physiology B/C

YES!!!
Very good! You got exactly what I wanted.
Your turn!
Yay :D

Explain the dangers of a mother being Rh- and her fetus being Rh+ and explain why usually only the second child is at risk.

Re: Protein Modeling C

Hey, so this is what I did to select the section to be modeled. First, did I do it correctly? Second, how do you manipulate it to get it to display the amino acid numbers for the alpha helices, beta pleated sheets and key amino acids? Looks correct to me! I don't believe that there is a specific fu...

Re: Protein Modeling C

Cysteine (Cys, C) and Methionine (Met, M) both contain sulfur. Cysteine forms disulfide bonds. Methionine cannot form disulfide bonds because the sulfur it contains is connected to a methyl group.
Exactly correct, your turn!

Re: Anatomy & Physiology B/C

I guess I'll just ask a question to get the marathon up and running again... Which of the leukocytes primarily target parasites, and how do they (leukocytes) destroy them (parasites)? I only know the first part, but i believe it is...|Eosinophils, and for the second part I'm going to guess|Phagocyt...

Protein Modeling C

I'm surprised nobody's started this one up yet, but here goes nothing...
Today's question comes to you in three parts:

Name the two amino acids that contain sulfur and their one and three letter abbreviations,

Identify which one forms a disulfide bond

Explain why the other aa can't form such a bond
