Restriction enzymes are also known as restriction endonuclease which is used in the recombinant DNA technology because they have property of recognizing and cutting a specific DNA sequence.
Every restriction enzyme is different and different restriction enzymes recognize different sequences in DNA and cut them. Restriction enzymes are divided into 4 types of classes, type I, II, III, IV.
These different types of restriction enzymes cut different specific nucleotide sequence. Therefore the correct answer is restriction enzymes.
The other answer choices don't make sense Herbicide is a poison that kills plants, Pesticide is an insect killer, while a Growth Hormone is designed to help the plant grow not to put nutrients into the soil.
