Introduction:
The genetic composition of an organism is termed as genotype. The genotype may vary in many aspects. The physical appearance or the growth characteristic of an organism is termed as phenotype of that organism. The phenotype is influenced and characterized by the genotype.

- If lactose is present in a cell with the following genotype, will functional Beta – galactosidase and/or permease be made? LacIs, LacP+, LacOc, LacZ+, LacY- / LacI+, LacP+, LacO+, LacZ-, LacY+ Group of answer choices Both genes will make functional protein. Only Beta – galactosidase will be functional. Only permease will be functional. No functional proteins will be made.arrow_forwardwhy does a clone of cells produceonly one type of G-6-PD enzyme?
