TRUE
what do the different bands mean
what is the role of B-galactosidase
cuts lactose
how many histone modifications are there
around 20
T/F: housekeeping is a type of dispersed promoter
True
When a mRNA level is over 1 ....
it is suddenly important and more mRNA is created
Why do the DNA move at different places
the size and weight
When there is lactose and high glucose what will happen?
The lacI will fall off and there is no cAMP, slow transcription
