DNA's stability arises from phosphodiester bonds protecting bases and hydrogen bonds linking base pairs; higher guanine-cytosine content, with three hydrogen bonds per pair, further enhances stability.
DNA is stable due to phosphodiester bonds protecting bases and hydrogen bonds linking base pairs. More guanine-cytosine pairs (with 3 H-bonds) increase DNA stability.
| Front | Why is DNA a stable molecule |
|---|---|
| Back | phosphodiester bond protect more chemically reactive organic bases Hydrogen bonds link organic base pairs and form bridges between phosphodiester uprights. As Cystine and guanine have 3 Hydrogen bonds. The more Cystine and Guanine the more stable the DNA molecule |
