The correct base pairing for DNA is
adenine → thymine and guanine → cytosine
adenine → guanine and thymine → cytosine
adenine → cytosine and guanine → thymine
adenine → adenine and cytosine → cytosine
Wyjaśnienie
In DNA, the correct base pairing follows a specific pattern: adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C). These pairs are held together by hydrogen bonds.
i.e A → T
G → C
