Hypothesize how other operons encoding catabolic enzymes might be regulated by catabolite repression
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.
Hypothesize how other operons encoding catabolic enzymes might be regulated by catabolite repression
In prokaryotes, all the functionally related proteins are present together in their genome. These structures are called operons. The transcription of all the genes in an operon is controlled by a single promoter. So, when these genes are transcribed, a polycistronic (two or more distinct mRNAs are present) mRNA molecule is produced.
The arrangement of genes in prokaryotes in the form of an operon allows for easy regulation of the entire biochemical pathway. Depending on the requirement, either the entire pathway can be inhibited or activated. This also conserves energy by preventing the expression of genes that are not required by the organism.
