Final answer:
The DNA bases that pair with each other are adenine with thymine, and guanine with cytosine. Adenine and thymine share two hydrogen bonds, while guanine and cytosine share three hydrogen bonds.
Step-by-step explanation:
The two DNA bases that pair with each other are adenine (A) and thymine (T), and guanine (G) and cytosine (C). Adenine always pairs with thymine, and guanine always pairs with cytosine.
The number of hydrogen bonds shared by each pair differ. Adenine and thymine (A-T) pairs share two hydrogen bonds, while guanine and cytosine (G-C) pairs share three hydrogen bonds.
For example:
- A and T are bonded together by two hydrogen bonds.
- G and C are bonded together by three hydrogen bonds.
