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.
