Question

The molecular basis of the Gram stain is the amount of _______ in the bacterial cell wall. bacteriophage spirochete peptidoglycan mycobacterium

Answer 1

Answer;

peptidoglycan

The molecular basis of the Gram stain is the amount of peptidoglycan in the bacterial cell wall.

Step-by-step explanation;

• Gram stain is differential stain that is very useful for identifying and classifying bacteria as either gram negative or gram positive.
• Gram negative are those that decolorize easily, such as E. coli, while Gram positive are those that retain the primary stain and do not decolorize easily.
• The result depends on the bacteria cell wall structure, the cell wall of a Gram-negative bacterium is composed of 20 percent or less of peptidoglycan.
