Each of DNA's four kinds of bases can pair with
only one of the other DNA bases. Using the base-
pairing rules, which of the following is the correct
order of bases that would pair with the following
string of bases on a DNA molecule:
Adenine, guanine, guanine, cytosine, thymine,
adenine
O A. Cytosine, thymine, thymine, adenine,
guanine, cytosine
O B. Thymine, cytosine, cytosine, guanine,
adenine, thymine
O C. Thymine, adenine, adenine, guanine,
cytosine, thymine
O D. Guanine, adenine, adenine, thymine,
cytosine, guanine

Answer:

The correct answer is - B. Thymine, cytosine, cytosine, guanine, adenine, thymine.

Explanation:

According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T)  and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.

Here, the bases are -

Adenine, guanine, guanine, cytosine, thymine,  adenine

the string of their base pair would be:

Thymine, cytosine, cytosine, guanine, adenine, thymine.
