Question

The structures of antibodies, DNA molecules and enzymes are specific to their actions. Which feature of each molecule makes it specific? antibody DNA enzyme A active site binding site base order B base order active site binding site C base order binding site active site D binding site base order active site

Answer 1

Answer:

We have seen that each type of protein consists of a precise sequence of amino acids that allows it to fold up into a particular three-dimensional shape, or conformation. But proteins are not rigid lumps of material. They can have precisely engineered moving parts whose mechanical actions are coupled to chemical events. It is this coupling of chemistry and movement that gives proteins the extraordinary capabilities that underlie the dynamic processes in living cells.

In this section, we explain how proteins bind to other selected molecules and how their activity depends on such binding. We show that the ability to bind to other molecules enables proteins to act as catalysts, signal receptors, switches, motors, or tiny pumps. The examples we discuss in this chapter by no means exhaust the vast functional repertoire of proteins. However, the specialized functions of many of the proteins you will encounter elsewhere in this book are based on similar principles.

Answer 2

Answer:

D

Explanation:

beacause binding site of antibody make it attach to specific antigen .

base order DNA codes for specific protein .

active site of enzymes form complex with specific substrates only.

I hope this is helpful to you .
