BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Hydrogen bond (H-bond) binds the nitrogen bases between the two strands of DNA.

Detailed explanation-2: -The base pairs are stabilized by hydrogen bonds; adenine and thymine form two hydrogen bonds between them, whereas cytosine and guanine form three hydrogen bonds between them.

Detailed explanation-3: -Base Pair The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.

Detailed explanation-4: -DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide.

Detailed explanation-5: -Nitrogenous bases make hydrogen bonds that let them pair up with their partner. In DNA, it’s G to C and A to T. In RNA, U takes the place of T.
