IMAT Gene regulation and the lac operon questions
35 questions · Biology
How bacteria switch genes on and off, using the lac operon as the model: the promoter, operator, repressor and the role of lactose.
Sample questions
- The prokaryotic operon is:
- AA DNA sequence element without any type of regulatory function
- BAn RNA complex that is involved in the replication of DNA
- Ca protein complex that catalyses the process of protein synthesis
- DA functional unit composed of a group of adjacent genes, co-ordinately controlled, and of DNA sequences with regulatory functions.
- EA group of adjacent genes independent from each other
