  ans. C. cervical cancer – HPV 16 E6 protein.

- The E6 protein of cancer-associated human papillomavirus type 16 binds to p53 and promotes its degradation through the ubiquitin–proteasome pathway.
- A mutant E6 gene that failed to reduce p53 could not delay cell death.
- Recall that P53 is a tumor suppressor gene. So when a tumor suppressor gene is out of wack. So the bodies start making antibodies.

  1- Not Sure, picked the same answer and got it wrong...But I'm thinking B....
2 - Pyelonephritis - Several episodes of UTI + Mild increase in Leukocytes
3 - Have you ever thought about quitting to smoke - This is what I picked, and I got it correct
4 - Uterine Relaxation - Beta 2-receptors + FEMALE experimental animals
5 - Aseptic Necrosis - Kinda went with the fact that there was no Inflammation.... But I got this one right too, but sorry about not having a better explanation.

STILL NEED THE ANSWER TO NUMBER 1 = PLEASE HELP!!!!
