Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of bond holds together the two strands of the DNA double helix?
A
Hydrogen Bond
B
Peptide Bond
C
Ionic Bond
D
Disulfide Bond
Explanation: 

Detailed explanation-1: -hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.

Detailed explanation-2: -Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.

Detailed explanation-3: -Each DNA molecule consists of two nucleotide chains wrapped around each other in a double helix and held together by hydrogen bonds. This hydrogen bonding involves only the nitrogenous bases.
