Answer to Question 1

Ans:
C

Feedback:

The proliferative potential and self-renewal of stem cells make them a compensatory mechanism and reserve source for the entire hematopoietic system. While they could be of possible use in certain autoimmune conditions or in cases of organ failure, these statements do not capture their essence. Stem cells can also come from a histocompatible donor.

Answer to Question 2

Ans:
C

Feedback:

One of the more studied translocations is the Philadelphia chromosome, which was the first chromosomal abnormality identified in cancer. Cytokines or chemical messengers, such as interleukin (IL)-1, IL-4, IL-6, and interferon, act synergistically to support the functions of the growth factors. BRCA is a genetic test for breast cancer testing. BRCA mutations place the female at risk for developing cancers of the breast and ovary; PSA stands for prostate-specific antigen. It is a protein produced by prostate cells and is utilized to screen for prostate cancer.
