WebBecause of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. shows the thymine-adenine bond. Each charge shown is ±e, and the H−N Question: The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). WebApr 8, 2024 · Cytosine forms three hydrogen bonds with guanine in DNA and RNA. This device, however, is unstable and can transform into uracil. This is known as spontaneous deamination. If DNA repair enzymes such as uracil glycosylase do not repair the damage by cleaving uracil in DNA, a point mutation may result.
