Answer: In DNA, each base occurs in a complementary pair with another base: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Since the percentage of T in the sample is 22%, we know that the percentage of A, which pairs with T, is also 22%.

The total percentage of the four bases in DNA must add up to 100%, so we can use this information to find the percentages of the other two bases, C and G. Since A and T make up 44% of the sample, we subtract 44 from 100 to get the percentage of the remaining two bases:

100% - 44% = 56%

The remaining 56% of the sample must be divided evenly between C and G, since they always pair with each other. So we divide 56% by 2 to get the percentage of each base:

56% / 2 = 28%

Therefore, the percentages of the four bases in the DNA sample are:

Adenine (A): 22%

Thymine (T): 22%

Cytosine (C): 28%

Guanine (G): 28%
