In an experiment you perform the following- you attach a flag epitope to HDAC, you over express a mutated Mad1-pro gene within the experimental cell, you immunoprecipitate the protein complex using flag epitope and run that on a non-denaturing SDS PAGE and western blot. Now you add antibodies for HDAC, MAD1 and SIN3A stripping after each addition. What will you observe?

Bands at same position every time

3 bands at different positions one at a time

Bands at same position on 2 occasions

In a substrate X catabolic gene promoter you replace the normal histones by your experimental histones ones with arginine side chains in place of histidine. What will be the effect on the concentration of substrate X against the control?

Concentration will fluctuate and no definite result will be obtained

Concentration will remain constant

Concentration will fluctuate and no definite result will be obtained
