Question

5. The diagram below represents an incomplete section of a DNA molecule. The boxes represent unidentified bases.

When the boxes are filled in, the total number of bases represented by the letter A (both inside and outside the boxes) will be
a. 4
b. 2
c. 1
d. 3

Answer 1

Step-by-step explanation:

There will be a total number of 3 bases that are represented by letter A. Adenine pairs with thymine and there are two thymine bases, which are paired to two adenine bases. There is an additional adenine base on the outside and accounts for the three adenine bases inside and outside.
