WebGuanine The DNA double helix is a stable structure. Its structure is similar to a ladder. The antiparallel sugar-phosphate backbones form the supports of the ladder, and the base pairs form its rungs. How is it possible for the bases to fit within the double helix or ladder? Pyrimidines always bond with a purine. Which base is shown in the diagram? WebApr 11, 2024 · The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.

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. I m a g e w i l l b e u p l o a d e d s o o n news robot

WebJan 14, 2024 · In double stranded DNA, the guanine (G) base on one strand can form three H-bonds with a cytosine (C) base on another strand (this is called a GC base pair). The thymine (T) base on one strand can form two H-bonds with an adenine (A) base on the other strand (this is called an AT base pair).
