Clostridium botulinum

Clostridium botulinum is clinically significant bacteria, which cause a very rare but a severe disease called “Botulism”. It produces a particular type of exotoxin that affects the nervous system by inhibiting the activity of neuromuscular junction.

Excision Repair

Excision repair is one of the types of DNA repair systems, which is an enzymatic process and follows a cut, copy and paste mechanism. A cutting mechanism involves, removal of the damaged part or unusual bases by the specific enzymes like glycosylases and helicases. Then a copying mechanism consists of an enzyme DNA-polymerase I, uses …
