Jacob and Monad studied lactose metabolism in E.Coli and proposed operon concept. Operon concept applicable for : -
1 All prokaryotes and all eukaryotes
2 All prokaryotes and some eukaryotes
3 All prokaryotes and all eukaryotes
4 All prokaryotes and some protozoanes
Explanation:
Operon concept proposed by Jacob Monad. This concept only applicable in the all prokaryotes. In genetics, an operon is a functioning unit of DNA containing a cluster of genes under the control of single promoter.

The Lac Operon is turned on when allolactose molecules bind to :
1 Promoter site
2 Operator site
3 mRNA
4 Repressor protein
Explanation:
The Lac operon is turned on when the allolactose molecules bind to repressor protein. The Lac repressor acts as a lactose sensor. It normally happen when the lactose molecules are converted to allolactose which binds to the repressor molecule. It the inducer such as lactose or allolactose is present, the repressor is inactivated by interaction with the inducer. It allows RNA polymerase access to the promoter and thus transcription proceeds.A

In negative operon
1 co-repressor binds with repressor
2 co-repressor does not bind with repressor
3 co-repressor binds with inducer
4 c-AMP has negative effect on lac operon
