| D. Taq polymerase | 1. Extends primers on genomic DNA template |
Explanation:
- Chitin is a complex carbohydrate found in the exoskeleton of arthropods, insects and fungi. Chitinase is an enzyme that hydrolyzes chitin, breaking it down into smaller components.
- DNA ligase is an enzyme that catalyzes the joining (ligation) of DNA fragments together. It plays a crucial role in the formation of recombinant DNA during cloning.
- Cellulose is a polysaccharide found in the cell walls of plants. Cellulase is an enzyme that hydrolyzes cellulose into glucose and other products.
- Taq polymerase is a thermostable DNA polymerase derived from the bacterium Thermus aquaticus. It is commonly used in the polymerase chain reaction (PCR) to extend primers and amplify DNA segments.
