Answer 1

Ans-14) Protein synthesis in prokaryotes is associated with- a) ribosomes.

In prokaryotes, protein synthesis occurs in the ribosomes mainly.

Ans-15) Differential stains are- a) Gram stain and acid-fast stain.

In differential staining, more than one chemical stain is used. Gram stain and acid-fast stain are types of differential staining.

Ans-16) The correct order of reagents used in gram staining is- Crystal violet- iodine solution- ethyl alcohol- safranin.Hence, the correct answer is (a).

Ans-17) The part of E. coli that serves as an endotoxin is- (c) LPS(Lipopolysaccharide).
