What is a regulatory gene?
The regulatory gene is a gene that determines whether the genes will be expressed. Also known as regulatory genes, some regulatory genes relate to a specific gene, while others can handle a group of related genes. These genes are produced by all organisms and are an important part of the system of controls and balance used for medium genetic expression, so the body works effectively and efficiently. The regulatory gene can respond to environmental pressures, as when an activator in a bacterium activates an antibiotic resistance gene when the body is around antibiotics. In complex multicellular organisms, regulatory genes are involved in the cell differentiation process and determine what the cell develops into. This allows organisms to have great diversity in cell types, so everything from neurons to skin cells.
Othetgens r act as repressors and shutdown of genes so that they cannot express. Like activators, suppressors can go into action in response to a number of different things, including environmental pressures and the needs of the EmbugYonal development. These genes can do things such as prevention of RNA transcription so that genetic material cannot be used. This type of regulatory gene can also act to suppress a harmful gene and maintain a healthy organism.
Like other genes, regulatory genes contain information that is used to coded proteins. They are rewritten to RNA that use cells to create proteins that these genes are designed to expresses. After creation, the protein can act in different ways on the genetic material inside the cell, depending on what to do. For example, the regulatory gene can create a protein that is locked to a part of the DNA so that it cannot be rewritten.
The identification of regulatory genes is performed by studying genome, finding specific genes, investigating the proteins for which they code, and studying the effect of these proteins. Scientists working with organisms such as fruit flies can do things likeTurn off the genes or on and then observe the results to learn more about what these genes do. In organisms, such as humans, where genetic manipulation is not considered ethical, scientists can compare genetic information among many people to seek common features and differences, using this information to narrow the function of specific genes.
