Question

dna is made of two chains of nucleotides. which type of bonds hold the chains together? hydrogen bonds covalent bonds ionic bonds polar covalent bonds

Answer 1

The correct answer is option A. Hydrogen bonds keep the two strands of DNA together by binding the nucleotides together. The hydrogen binding is repsponsible for the stability of DNA. The N-H bonding is the reason behind this between nucleotides base pairs of the DNA.

Answer 2

The appropriate response is hydrogen bonds. It is a feeble bond between two particles coming about because of an electrostatic fascination between a proton in one atom and an electronegative iota in the other. Intermolecular hydrogen holding is in charge of the high breaking point of water (100 °C) contrasted with the other gathering 16 hydrides that have significantly weaker hydrogen bonds.
