Archaeal and Bacterial pili are identical in structure and function.

Question

Quizplus · Accepted Answer

Although some similarities exist between archaeal and bacterial pili, their structures and functions are different. Archaeal pili are usually thinner and more flexible, and they are involved in motility, biofilm formation, and cell-cell interaction. Bacterial pili, on the other hand, are usually thicker and stiffer, and they are involved in adhesion, DNA uptake, and twitching motility.
