if a mutation is found in the gene that codes for the Lacl repressor protein gene, the protein no longer performs its intended function. Explain what would be the outcome at the gene level and for the E coli.
the only thing that i can think of is transcription will occur ? can you answer the questions please :)

You are basically right. With the repressor not working, the lac genes will be freely transcribed. The lac genes code for proteins involved in the breakdown of lactose in E.coli. Proteins are very complex and require a lot of energy to be made. If the lac proteins are always being made, even when unneeded, there will be a build up of these proteins and the cell will lose a lot of energy by constantly producing unneeded proteins.
