Question

Affinity chromatography deals with (1) specific binding between two biological molecules (2) protein-protein interaction (3) protein-carbohydrate interaction (4) none of the above

Answer 1

The nitrogenous bases form hydrogen bonds between opposing DNA strands to form the rungs of the "twisted ladder" or double helix of DNA or a biological catalyst that is found in the nucleotides. Adenine is always paired with thymine, and guanine is always paired with cytosine. These are known as base pairs.

Answer 2

Explanation:

☑️ Chromatography can be used to separate protein in solution or denaturing conditions by using porous gels. This technique is known as size exclusion chromatography. The principle is that smaller molecules have to traverse a larger volume in a porous matrix.
