The correct base pairing for DNA is:
A. adenine → thymine and guanine → cytosine 
You can use this to remember 
:
A 
T (both have straight lines)
G C (both have curves)
And guess what? These base pairs are held together by 𝙝𝙮𝙙𝙤𝙜𝙚𝙣 𝙗𝙤𝙣𝙙𝙨:
A and T have 2 hydrogen bonds (not too clingy)
G and C have 3 hydrogen bonds (super tight bond!)
