What does the correlation coefficient indicate about the similarities between the gene expression profile for mike smith and the gene expression profile for patient 4? what does this number indicate about how mike smith's cancer might respond to drug 4?

They are identical

Explanation:

The gene profiles show that the profiles are identical. This can be done in several ways. One way is to compare the DNA in the profiles. This is done by running the electrophoresis. The process of electrophoresis is premised on the fact that the DNA is of the acidic nature and has a mass. The mass of the DNA is determined by the amino acids in the molecule. In addition, the DNA has a charge. The DNA is put into the conductive paste and the test done. The separation of the DNA is compared to the profile of patient. If the bands separate at equal distances, then the profile for patient 4 will be that for Mike.
