A basic dye used in gram staining is crystal violet.
Gram +'ve = purple/blue
Gram -'ve = pink/red
Gram straining
basic dyes are more effective for bacterial staining than acidic dyes because basic dyes have a positive charged chromogen. Bacterial nucleic acids and certain cell wall components carry a negative charge that strongly binds to the cationic chromogen.

Methylene blue a basic stain is generally used to identify the external morphology of bacteria.The other stain which is used as differential stain and which can also differentiate the baceteia on the basis of their cell wall is gram stain i.e. Crystal voilet and is counter stained with Saffranine
Crystal violet, basic fuchsin, and safranin are all dyes which can be used in direct staining because they are cationic which means that they are positively charged. These dyes which are positively charged will react to the bacterial cell wall because the cell wall is negatively charged resulting in a basic stain.
Post and lintel is the most basic architectural technique for spanning space.
Sure, any basic stain can be used for simple, direct staining.
the two basic types of diseases are viral and bacterial
Distillation is a basic technique

Basic Motion Picture Technique - 1947 was released on: USA: 8 December 1947
The bacterial cell wall has a negative charge. The basic stain has a positive charge. Since they have opposite charges, the bacterial cell wall and the basic stain are attracted to each other; hence the basic stain dyes the bacteria.
understanding the keyboard is the basic operational technique in typing using ms word application.
Which technique can be used to make multiple copies of a gene? What are the basic steps in this procedure?
basic dyes are more effective for bacterial staining than acidic dyes because basic dyes have a positive charged chromogen. Bacterial nucleic acids and certain cell wall components carry a negative charge that strongly binds to the cationic chromogen.
