The component of bacteria that retains the crystal violet stain during Gram-staining is
- O-antigen
- Lipopolysaccharide
- Peptidoglycan
- Cytoplasmic membrane
The Correct Option is C
Solution and Explanation
The stain is retained by the peptidoglycan layer within the cell wall of the bacteria. They are classified into gram positive and gram negative. Gram positive has a thick layer of peptidoglycan, that prevents the stain from washing away. Gram negative on the other hand, has a thin layer of peptidoglycan.

- Ruma reached the metro station and found that the escalator was not working. She walked up the stationary escalator with velocity \( v_1 \) in time \( t_1 \). On another day, if she remains stationary on the escalator moving with velocity \( v_2 \), the escalator takes her up in time \( t_2 \). The time taken by her to walk up with velocity \( v_1 \) on the moving escalator will be:
