Answer to Question 1

ANS: B
A chromosomal mosaic means the body has two or more different cell lines, each of which has a different karyotype; thus, the person has a mild form of the disease. Mosaics are not only carriers; they have the disease; they have two different lines but not two different diseases; and they are not necessarily sterile.

Answer to Question 2

ANS: C
The four base components of DNA are cytosine, thymine, adenine, and guanine, and are com-monly represented by their first letters (A, C, T, and G) and not components identified as P or U. X, XX, XY, and YY are components of human chromosomes.
