Question

In DNA, how many hydrogen bonds form between guanine and cytosine?

Short answer

There are $3$ hydrogen bonds form between guanine and cytosine

Step-by-step solution

Given information

We need to find hydrogen bonds form between guanine and cytosine

Simplify

Because their accessible hydrogen bond donors and acceptors couple with each other in space, guanine and cytosine form a nitrogenous base pair.
Guanine and cytosine are said to be mutually beneficial.
