Question

Quizplus · Accepted Answer

Basic dyes are positively charged, and most bacterial surfaces are negatively charged due to the presence of cell wall components like teichoic acids, lipopolysaccharides, and peptidoglycans. This charge interaction leads to the attachment of basic dyes to most bacterial surfaces.
