In Gram-positive bacteria, what is the function of teichoic acids in the cell wall?
Show answer and explanation
Correct answer: Provide negative charge and rigidity
Teichoic acids are anionic polymers in Gram-positive cell walls that help maintain cell wall rigidity and contribute to the overall negative charge of the bacterial surface.
