The lac operon consisting of lacl, lacZ and lacY genes in addition to all the transcripton factors is used to modulate the level of lactose in the cell. Please describe the cycle of fluctuations in lactose levels and why they occur by referencing the specific components. If glucose is a byproduct of this process, how are the glucose levels in relation to the lactose level fluctuations and the reason for those fluctuations?
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
