Answer:
The main bonding in DNA which renders the double helix structure so stable is that of hydrogen bonds. ... As well as this there are hydrogen bonds between the bases and surrounding water molecules, and this combined with the even stronger phosphodiester bonds in the sugar phosphate backbone make DNA very stable.
Explanation:Which strand of DNA is more stable?
G-C base pairs have 3 hydrogen bonds, while A-T base pairs have two. Therefore, double-stranded DNA with a higher number of G-C base pairs will be more strongly bonded together, more stable, and will have a higher melting temperature.
Why is DNA stable in alkaline conditions?
DNA is stable in alkaline conditions. It has smaller grooves where the damaging enzyme can attach which makes it harder for the enzyme to attack DNA; RNA, on the other hand, has larger grooves which makes it easier to be attacked by enzymes.
