Bacteria with single flagella at one end is called
1 monotrichous
2 lophotrichous
3 amphitrichous
4 peritrichous
Explanation:
Monotrichous bacteria:- When a single flagella is present at one end bacteria is called monotrichous. eg Pseudomans, Vibrio cholerea.

How many linear DNA fragments will be produced when a circular plasmid is digested with a restriction enzyme having 3 sites?
1 4
2 5
3 3
4 2
Explanation:
When the plasmid contain 3 recognition sequences for a given restriction endonuclease, 4 linear DNA fragment are produced because circular DNA produces N-recognition sequences for the same restriction endonuclease whereas linear DNA produces $(\mathrm{N}+1)$ fragments.

Splenic fever occurs in cattles, goats, camel and sheep etc, and is caused by
1 Corynebacterium pyogenes
2 Cowpox virus
3 Klebsiella pneumoniae
4 Bacillus anthracis
Explanation:
Splenic fever occurs in cattles, goats, camel and sheep etc and its caused by Bacillus anthracis. It is a Gram-positive and rod-shaped bacterium that is occasionally pathogenic to humans.
