Question

How are eukaryotic genes expressed or not expressed

Accepted Answer

Gene switched off and unexpressed if repressor molecules bind to operator genes or they bind to regulator proteins to prevent them from binding to the operator gene; gene switched on and expressed if RNA polymerase attaches to operon (and sometimes a regulator protein must be attached also to trigger transcription)
