Which nitrogen base sequence is the partner of T-C-A-G-C-A? A-C-G-A-C-T
C-A-G-A-T-G
A-G-T-C-G-T
T-C-A-G-C-A

A-G-T-C-G-T

Explanation: 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.
