You want to find out which of the consequent gene X or Y is being transcribed. For this you do a hybridization competition analysis and plot the radioactivity curve with increasing concentration of the competitor unlabelled mRNA. If the transcribed gene was X, which observation fits your result?(a) The radioactivity of y decreases while that of x remains the same(b) The radioactivity of x decreases while that of y remains the same(c) The radioactivity of x and y decreases(d) The radioactivity of y decreases while x increasesThis question was addressed to me in an online interview.My enquiry is from Transcription in Prokaryotes : Initiation topic in portion Gene Expression : Transcription Prokaryotes of Cytogenetics
