Looking at your E3 sample, what would you estimate the purity of rGFP in the E3 fraction? (Hint: look at the overall intensity in one lane, what percentage of that overall intensity is due to the rGFP band? Do not look at the number of bands to estimate the purity.) g

b.

the accuracy of the data.

sup bro, im dumb, but this is what i found xd

"the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface"
