They were told that RGN1 is a mating mutant. You have identified a free-swimming algae that regulates its internal temperature by concentrating or dispersing pigment filled vesicles. Enthralled, you decide to study these vesicles and their movement. When the temperature is cooler the PV are moved to just under the plasma membrane so that they can help to capture solar energy. The motors appear to be the same as those used in mammalian systems.
Microtubules are polymers.
You decide it would be prudent to add a drug to stabilize the microtubules in your algae PV movement assay. Briefly describe how a microtubule stabilizing drug would effect mating in yeast. Microtubules are not static structures. Discuss the role of nucleotides in the process of dynamic instability. These algae have a unique mechanism for dealing with extremes in heat.
