Question

Bacterium is treated with lipotechoic acid, an inhibitor of autolysin . Which of the following is a likely outcome? Select one: a. Bacterium will not be able to replicate its chromosome. b. Bacterium will not be able to undergo transformation. c.Bacterium will not be able to produce a sex pilus. d. Bacterium will not be able to add new peptidoglycan subunits to its cell wall during the bacterial cell cycle.

Answer 1

After treatment with lipotechoic acid, bacterium will not be able to autolysin ( means self digestion ) . Lipoteichoic acid is present naturally in the cell wall of bacteria.
the answer to this question is that bacterium will not be able to transform as autolysin will not occur.

we can directly link the answer through the word given autolysin.
and as it is present in cell wall so, we can eliminate another options like chromosome or sex pilus.

In solving mcqs we need to learn elimination technique. To eliminate the odd one first.
