Beat frequency difference between the two flagella of Chlamydomonas depends on the attachment site of outer dynein arms on the outer-doublet microtubules.

Abstract excerpt

The two flagella of Chlamydomonas, although similar to each other at first glance, differ in functional properties. A clear difference exists in the beat frequency: the trans-flagellum (the one farthest from the eyespot) beats with 30-40% higher frequency than the cis-flagellum (the one nearest to the eyespot) in demembranated and reactivated cell models. This difference is considered to be influenced by outer...
