What is an operon?
1.Operons are sets of genes found in bacteria that are used for a shared metabolic pathway.
2.Operons are genes in eukaryotes used in development
3.Operons are sequences in prokaryotes that code for the ribosomal RNA
4.Operons are genes that have been recently transferred between bacteria
Homework Answers
Operons are found in prokaryotes, operons, contains multiple genes, products of which are involved in a particular metabolic pathway and the genes are transcribed together in a single mRNA, so the expression of these genes are regulated together, so the answer is
1.Operons are sets of genes found in bacteria that are used for a shared metabolic pathway.

The Lac operon is an inducible set of genes found in bacteria cells that helps the bacteria to metabolize the disaccharide lactose. When it is turned on it produces proteins that pump lactose into the bacteria cell and break it down into glucose and galactose, which can then be used by the bacteria as a source of energy The two figures below show the Lac Operon along with the lacl gene (which regulates the Lac operon...

29. An operon is a cluster of genes on a bacterial chromosome that are all involved in the same metabolic pathway. 30. Mutations that arise as a result of exposure to a mutagenic chemical are called spontaneous mutations. When an Hfr strain conjugates with an F. strain, the strain usually becomes Ft.
