What is Gel electrophoresis?

Gel electrophoresis may be defined as a type of laboratory methodology that is significantly utilized in order to separate mixtures of DNA, RNA, or proteins according to molecular size. This process is used to analyze the biomacromolecules and their fragments on the basis of their charge and size.

In this technique, the molecules that have to be separated are pushed by an electrical field through a gel that contains small pores. Before performing an actual mechanism, DNA is mixed with a dye known as Ethidium bromide and then loaded into wells which are formed by Acrylamide gel through the use of a pipette.

Therefore, before running the gel, DNA is mixed with dye and loaded into wells through the use of a pipette.

Answers

A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.

The correct answer is:

Option C. have a complementary shape to the substrate.

This can be explained as:

If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.

Activation energy is the minimum amount of energy needed for the reaction.

If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.

Therefore, the active site should have a complementary shape to the substrate.
