What are key markers for the identification of Bacteria?

1 Peptidoglycan in cell membranes, ether-linked fatty acids, Special transcription DNA

2 Special RNA polymerase, peptidoglycan in cell walls, ester-linked fatty acids

3 Cellulose in cell membranes, ester-linked lipids in cell walls, special transcription DNA

4 Special RNA polymerase, peptidoglycan in cell membranes, chitin and cellulose cell walls

Answer: Option B

Explanation:

There are some of the key markers which states that can differentiate bacteria from other organism.

These markers are special RNA polymerase, ester linked fatty acid and peptidoglycan layer.

The peptidoglycan layer in the cell wall of the bacteria which can be used as a target for all the drugs made as antibiotics.

The bacteria also has special RNA polymerase with four catalytic unit and single regulatory subunits.

The ester linked fatty acid differentiates it from Archae as they have ether linked fatty acid.

Answer

The key markers for the identification of bacteria are special RNA polymerase, peptidoglycan in cell walls. ester-linked fatty acids.
