Question 67513

The Central Dogma of Molecular Biology describes the flow of information in a cell. Briefly name and describe the two key processes that the cell performs in order to transmit and utilize genetic information. A full answer should include naming the template and the end product of each process, and the location of each process inside a eukaryotic cell.

Researchers have identified mutations in the coding region of the lacI gene that lead to a change in the structure of the lacI repressor protein. In these mutants the lacI protein’s allolactose binding pocket is now permanently in the ‘bound’ state. Explain fully what consequence, if any, this will have on the production of lacZ protein in the mutant E. coli cells.
