Answer #1

Gram + bacteria:

Gram-positive bacteria retain the color of the crystal violet stain in the Gram stain. This is characteristic of bacteria that have a cell wall composed of a thick layer of a particular substance (called peptidologlycan).

The Gram-positive bacteria include staphylococci , streptococci , pneumococci.

Gram -bacteria:

Gram-negative bacteria are bacteria that do not retain the crystal violet stain.

examples: E. coli, Pseudomonas aeruginosa.

Gram - bacteria is responsible for cancer development.Following flow chart helps in understanding how bacteria causes cancer

This is how bacteria causes cancer in human beings.

Question 18 4 pts What role do restriction enzymes play in bacteria? How do bacteria protect their own DNA from the action of restriction enzymes? Change the surface proteins of bacteria; since DNA is not protein, there is no need for protection Cut foreign DNA into pieces; bacteria have RNA genomes. Destroy invading viral DNA: bacterial DNA does not contain the restriction enzyme recognition sequences. Restrict the growth rate of bacteria; bacterial DNA is restriction enzyme resistant. Question 18 4...
