Answer 1

It’s the one with a t

That’s how I remember

Answer 2

Step-by-step explanation:

DNA means deoxyribonucleic acid. It is present in all the living beings and it is considered as the main component of chromosomes.

Bases present in a DNA molecule are adenine (A), guanine (G), cytosine (C), and thymine (T).

Also, it is known that adenine will always pair with thymine and vice-versa. Whereas guanine will always pair with cytosine and vice-versa.

Therefore, we can conclude that when two strands of DNA line up, adenine always pairs up with thymine.
