The native complexes of several kinesin family members have also been shown to contain additional peptides, often designated light chains as all of the noncatalytic subunits that are currently known are smaller than the chain that contains the motor unit. Kinesin complexes generally possess a force-generating enzymatic activity, or motor, which converts the free energy of the gamma phosphate bond of ATP into mechanical work."

Distributive segregation is a \"backup\" mechanism to ensure the segregation of homologs that have failed to cross over - either as a consequence of mutation or not, as, for example, the 4th chromosome of Drosophila melanogaster (which never exchanges, presumably due to its small size) - but nevertheless segregate normally."
