The promoter (P) is the start site of transcription through the binding of RNA polymerase before actual mRNAproduction. Mutated promoters (P) cannot bind RNA polymerase, so no mRNA is made. In the table below, makepredictions about the expression of ß-galactosidase and permease for different partial diploid (F') genotypes. Do this forE. coli growth on two different types of media - one without lactose, and one with. Use a to mark where there is noenzyme produced, and a + to mark where the enzyme is made. The first genotype has all wild-type alleles, and has beenfilled in as an example.GenotypeIPOCZ+Y/I-P+O+Z-Y+ISP+O+Z+Y/I+P+O+Z*Y*CR 1:00Lactose absentB-galactosidasePermeaseR 3:-00+R 6:30Lactose presentB-galactosidaseF 10:00Permease

1. Please tell me: What's a mutation in moleculer terms? 2. When a mutation deletes a base in genomic DNA, how does it affect the expression product production and reading frame? 3. How does induction control enzyme synthesis using lactose operon?
3. Bacteria are normally haploid organisms (1 copy of the genome), however it is possible to introduce a plasmid into the bacteria to create a pseudo-diploid situation. Here we have introduced a plasmid that carries the lac operon. Based on the following genotypes, predict the state of the beta-glactosidase enzyme (lac Z) in each of the following situations. I- = a mutation in the repressor protein that cannot bind to the operator Is = a mutation in the repressor protein that cannot be removed from the operator Oc = a mutation in the operator that cannot bind the repressor Z` = a mutation in beta-galactosidase that makes the enzyme non-functional Chromosome Lactose Present I, Z, O I, Z, O I.
