The expression of a hypothetical gene was analyzed by Northern and Western blot hybridizations under control and induced conditions. The results are summarized below:
Expression of genes can be regulated by:
P. Control at transcription initiation
Q. Alternative splicing
R. Control of translation initiation
S. Protein stability
Which of the above regulatory mechanisms can explain the observations shown in the figures?
1
Only Q
2
Both P and Q
3
Both Q and R
4
P, Q, R and S
5
