The flagellar filament in prokaryotes is primarily composed of which protein?
A
Myosin
B
Actin
C
Flagellin
D
Tubulin
Verified step by step guidance1
Understand that the flagellar filament is a key structure in prokaryotic motility, allowing bacteria to swim.
Recall that the filament is made up of a specific protein that polymerizes to form a helical structure.
Identify the proteins listed: Myosin and Actin are primarily involved in eukaryotic cytoskeleton and muscle contraction, while Tubulin forms microtubules in eukaryotes.
Recognize that Flagellin is the unique protein that polymerizes to form the flagellar filament in prokaryotes.
Conclude that among the options, Flagellin is the correct protein composing the prokaryotic flagellar filament.
