Answer #1

Depurination means removal of a purine from its site in the DNA structure. Adenine (A) and Guanine (G) are purine bases. If depurination is not repaired, then there will be a missing purine base (A or G) at the site of depurination.

Hence, correct choice should be:

(C) The DNA molecule is missing one nucleotide pair.

    “Unlike what happens in DNA replication, where both strands are copied, only one of the two strands is transcribed into mRNA. The DNA strand that contains the gene is sometimes called the sense strand, or coding strand, and the DNA strand that gets transcribed to give RNA is called the antisense strand, or noncoding strand. Because the sense strand and the antisense strand are complementary, and because the DNA antisense strand and the newly formed RNA strand are also complementary,...
