Question

Which of the following is NOT correct with respect to the mycoplasmas?
A) They have lost their cell wall and the S-layer through reductive evolution.
B) Their cells maintain their shape through a type of cytoskeleton.
C) When cultured on agar, their colonies have a "fried-egg" shape.
D) They are parasites of all kinds of multicellular organisms.
E) They have some of the largest bacterial genomes.

Accepted Answer

Mycoplasmas are known for having some of the smallest bacterial genomes, not the largest. This is due to their reductive evolution, where they have lost many genes not necessary for their parasitic or saprophytic lifestyles.
