A bacterial cell wall is mainly composed of
1 Mucopolysaccharides
2 Sialomuco protein
3 Peptidoglycan (murein)
4 Glycogen and muramic acid
Explanation:
: A bacterial cell is composed of mainly peptidoglycan (murein). It also contain lipid, protein and polysaccharide. The peptidoglycan contain, Nacetylglucosamine (NAG) and $\mathrm{N}$-acetyl muramic acid (NAM). - In addition to these constituent L - alanine and Dalamine, D-glutamic acid and diaminopimelic acids are also found.

Which cell is most minute and smallest freeliving organism?
1 Mollicutes
2 Bacterium cell
3 Prions
4 Viroids
Explanation:
: Mycoplasma or mollicutes is smallest and minute free-living organisms. They were discovered by Nocard and Roux (1898). They are cell wall devoid, pleomorphic. Gram negative Monera member with smallest cell size $(0.1-0.15 \mu \mathrm{m})$. These are popularly known as Pleuro pneumonia Like Organism (PPLO).

Circular free floating molecule of DNA duplex, autonomous, found in bacterial cytoplasm are extensively used as vector in genetic engineering
1 Cosmids
2 Phages
3 Plasmids
4 Bacterial DNA
Explanation:
: Plasmids are circular, free floating molecule of DNA duplex (extra-chromosomal DNA) autonomous, found in bacterial cytoplasm as (extrachromosomal DNA). These are extensively used as vector in field of genetic engineering to insert the desirable gene into organism.
