Answer:
Complementary base pairing is the phenomenon where in DNA guanine always hydrogen bonds to cytosine and adenine always binds to thymine. The bond between guanine and cytosine shares three hydrogen bonds compared to the A-T bond which always shares two hydrogen bonds.
Answer:
Cytosine
Explanation:
- Guanine always bonds with Cytosine, which makes them a pair of complementary bases. Adenine always bonds with thymine, making them DNA's other pair of complementary bases. These pairs form the “rungs” of the DNA ladder.
