The restriction enzymes are called as “Molecular scissors”. These act foundation of recombinant DNA technology. These enzymes are present in bacteria and provide a type of defense mechanism called the “restriction—modification system”. (a) What are molecular scissor? Give one example.
(b) Mention the role of “Molecular scissors” are recombinant DNA technology.
(c) How do the bacteria protect their own genome from these enzymes?

(a) Molecular scissors are the enzymes use to cut DNA . ex- Restriction Endonuclease .
(b) Yes it's a recombinant DNA Technology use to cut DNA segments for the production of new enzymes or antidotes.
(c) Bacterial methylases protect the host DNA by methylation in the sequences the restriction enzymes recognize, and the restriction enzymes fail to cleave methylated DNA.
