When two strands of dna line up, adenine always pairs up with?

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.

It's the one with a t

Apples in the tree (A to T)

Car in the garage (C to G)

That's how I remember
