Temperature-sensitive mutations in a kinesin ii required for intraflagellar transport (ift) have been identified in chlamydomonas. such mutations only lead to defects when the temperature is raised above a certain threshold, called the restrictive temperature. when algae with fully formed flagella are grown at the restrictive temperature, their flagella degenerate. what can you conclude about the necessity of ift from this experiment?
