Interpreting the spectrum

  This graph is made  up of two curves of DNA and HB along with GFP. At the beginning of each curve there is a little bit of noise which results in a more jagged curve.

The two DNA curves are said to peak at about 260nm. The native DNA curve peaks at two places, its highest peak is somewhere around 230nm while the smaller peak is around 270nm. The denatured DNA also peaked into places although its peaks are shifted to the right and not as tall.  In the denatured DNA the first peak is around 240nm while the second, smaller peak is near 280nm.

The two Hemoglobin's curves have two  peaks. The first peak for both the nature and denatured is around 230nm.  The second peak of the native HB is around 420nm while the denatured HB has its second peak around 280nm.

The GFP also has two peaks but on the graph it looks as if it is mimicking the denatured HB but with a smaller absorbance.  The GFP curve peaks around 210nm and then 270nm. Although the predicted literature value for GFP is a peak at 395nm and 475nm.
