This was probably one of the must interesting things we
ran across while testing these mutants. This mutant is called ida3 and
is missing the biggest of all inner arm dyneins, the I1 dynein. As you
can see from the video this mutant has an alternating stroke comparable
to a doggy paddle. These cell's motility was highly inhibited and
unproductive which leads us to the theory that the I1 dynein has the
biggest effect on regulation of the flagella.
