The Living WorldIn our Theory of Knowledge class students discussed their thoughts on the question What is art in a socratic seminar Students came to the consensus that art can mean many things and take on many different forms One student suggested that art is a physical representation of people s emotions According to them art invokes one or more of the senses like touch or taste Another student suggested that art is characterized by its usage of artistic elements like form and texture A third student suggested that art can also be a form of political protest They provided the example of a fashion show where everything the artists wore broke to demonstrate the ills of fast fashion I think that all three student s views basically encompass the essence of art I think that art can be defined by its purpose as well as the tools used to create it The conversation veered onto the topic of art s value One student suggested that humans value art based on how much we can interpret it Therefore professional artists can interpret things better compared to a regular person Another student disagreed with this arguing that art s value is not conditional on the person viewing it and that art has inherent value I personally agree with the second student An art piece s message doesn t waver depending on the person who views it Art is always subject to human interpretation Human interpretation is subjective but this doesn t disregard the art s value

The Living WorldQuestion 14 Studying bes To study motor function on microtubules scientists can create purified stable fluorescently labeled microtubules and motors different colors and watch movement of the kinesin walking along the microtubule using a fluorescence microscopy This allows scientists to analyze the kinetics of kinesin movement velocity of movement what regulates movement etc A How might you expect that molecular biologists create stable and labeled microtubules for this experiment To create stable and labeled microtubules for this experiment they would likely polymerize purified tubulin into microtubules in the presence of a fluorescent marker or dye The addition of a stabilizing agent like taxol can help block the microtubules dynamic instability and promote stability B Based on what you know about how kinesin motor activity is regulated by ATP ADP and nucleotide release what do you think would happen if you added only ADP to this experiment rather than ATP Would the kinesin ever bind the MT Would you observe the kinesin walking on the microtubule The movie 17 7 in the movies folder in Moodle might be helpful for this question Bio285 F23 If you only added ADP rather than ATP to this experiment the kinesin would bind to the microtubule because ADP bound kinesio has a good affinity for the microtubule That would cause a conformational change leading to ADP dissociating from the binding pocket Since there s no ATP to diffuse into the binding pocket of kinesio and cause the neck linker to change conformation and cause walking kinesin would bind to ADP and remain bound to ADP and therefore bound to the microtubule and no walking is observed C Based on what you know about how kipesin motor activity is regulated what do you think would happen if you added a n00 hdolzable ATP analog to this experiment Would the kinesin ever bind the MT Would you observe the kinesin walking on the microtubule Here is a structure of an example 000 bydrolyzable ATP analog ATP y S S 0 O P P P NH Topic 6 Problem Set Answer Key N O Francis N N
