Answer 2

Gram Strain have isolated a prokaryotic cell. The first step in identification

What is isolated prokaryotic?

In the DNA isolation procedure, the sample from which DNA needs to be extracted is taken and the sample is made to undergo cell lysis. In this, the cell wall is broken down and then the sample ire made to centrifuge at high speed. The cell debris is removed through this process. After these proteins are denatured using protease. Then they are made to precipitate using the organic solvents in the ratio of 1:1 of a mixture of chloroform and phenol.

Prokaryotes can be classified based on their shape and their Gram stain reaction. However, the Gram stain is not a reliable method of identifying archaea, as they do not contain peptidoglycan in their cell walls.
