Answer:

Adenine pairs with Thymine and Cytosine with Guanine. Thus :  A-G-T-C-G-T is the correct answer.

Explanation:  According to Watson and Crick DNA base pairing, purine bind to the pyrimidine base whereas each purine binds to a particular type of pyrimidine.

Like adenine (A) binds with thymine (T) and guanine (G) binds with cytosine (C) in a DNA molecule.

Since, the given sequence is T-C-A-G-C-A, therefore, its nitrogen base sequence is A-G-T-C-G-T.

Answer: C: C-G-T-C-G-A

Explanation: The match for G is C and vice versa. The match for A is T and vice versa for that too. So, looking at the first letter (G) of the original sequence, you need C to complement it. The only answer choice that starts with “C” is option C. If you continue looking, every other letter in that sequence is correctply partnere (G’s with C’s and A’s with T’s). Thus, C is the correct answer.
