they are not needed.
Operons:
 Enzymes that regulate the expression of genes
 Example:
▪ Lac operon: regulates the production of the enzyme that digest
lactose

Environmental factors can affect the regulation
and expression on organisms.
Examples:
 Temperature/weather
 Number of females and males in the population
 Products with carcinogens
 Radiation (UV Light)
