Post by: nerdy4u on Apr 22, 2015
Table I: Record the results of using knockout strains of the plant Arabidopsis to determine gene function.
Plant   Optimum  Growth Conditions   UV Exposure   High Salinity in Soil   Drought Conditions
Wild-type            
Mutant 1            

Questions:

1.   The knockout mutants of Arabidopsis used in this exercise each have _____.






2.    When making your experimental observations in this exercise, you are observing which structures?







3.    High salinity and drought conditions may both cause Arabidopsis plants to become _____.







4.    In your experiments, you expect to see normal growth in both the wild-type and mutant plants under which condition?






5.    In your experiments, you can determine the role of the knockout gene by seeing which condition produces wild-type and mutant plants with _____.

Do you know how to fill in the chart? I answered rosette leaves for #2, Optimum for #4, and #5 diff phenotypes...

To be honest, nerdy4u, I obtained these answers from a secondary source, so I am not entirely sure if they are correct. I was hoping you'd be knowledge enough to decipher if they fit with your studies.
