Web23 jul. 2024 · How many hydrogen bonds are in three turns of DNA? In three turns there will be 30 base pairs of DNA or 60 nucleotides. So 12 nucleotides are thymine. thymine is double bonded with hydrogen bonds with adenine so 12 nucleotides are adenine according to Chargaff’s rule. So it will have 24 hydrogen bonds. Web6 okt. 2024 · The short answer is heat. Compared to the covalent phosphodiester bonds, hydrogen bonds (H-bonds) are very weak, and they're much easier to break and re-form. A long enough piece of double-stranded DNA will stick together at physiological temperature because it contains thousands of highly coordinated hydrogen bonds.
