You have developed an activator of a non-receptor tyrosine kinase. In three different cell types that all contain this receptor your drug has different effects. In cell type A you see activation of gene X and gene Y; in cell type B you note activation of Gene X, but no change in the mRNA levels for Gene Y. In cell type C your drug has no effect on either Gene X or Y. Describe how could each choice (A-D) be...

You
perform an assay on the activity of the JAK tyrosine kinase using a
40 microliter aliquot of a lysate prepared from cells labeled for
six minutes with radioactive cysteine. the total volume of the
lysate is 5 milliliters (ml). In the aliquot, you measure the
amount of all proteins and determine the presence of 13 micrograms
of protein in 75 microliters of lysate. which of the following is
the best calculation of the specific activity of the kinase in...
