The genes are controlled by the control elements in their upstream sequence. It can also regulated at RNA level by si, sh RNAs. The regulation is basically influenced by the surrounding environments. Proteins mediated the regulation of gene expression.
Genes that are turned off are called "repressed genes." This means that they are not actively being expressed or producing proteins in the cell.

What turns the lac operon on and off?
The lac operon is turned on when lactose is present in the environment and glucose is scarce. This leads to the activation of the lac repressor protein, allowing the expression of genes involved in lactose metabolism. The lac operon is turned off when lactose is absent or glucose is abundant, which prevents the unnecessary expression of these genes.
What are the factors that control a trait called?
The factors that control a trait can include genetic influences (such as genes and alleles), environmental influences (such as diet and exposure to toxins), and the interactions between genetics and the environment. Additionally, epigenetic factors can also play a role in the regulation of gene expression and the manifestation of traits.
What is the difference between heterochromatic and euchromatic regions of the genome?
Heterochromatic regions of the genome are tightly packed and less active, containing genes that are usually turned off. Euchromatic regions are loosely packed and more active, containing genes that are typically turned on.
Genes located in different regions of the body during embryonic development may be which turned on and off never turned on turned on and left on activated for different times in different cells or all?
Genes located in different regions of the body during embryonic development may be turned on and off, activated for different times in different cells. This dynamic regulation helps to control cell differentiation and tissue formation.
Why are all genes not active all the time?
Genes are not active all the time because different genes are needed for different functions in the body. The process of gene regulation allows cells to control which genes are turned on or off at any given time, allowing for the proper functioning of the body's processes.
The test that is used to determine the pattern of genes that are turned on or off in cancer cells is called?
Pedigree
Are all of organism's genes turned on at the same time?
No, not all of an organism's genes are turned on at the same time. Gene expression is tightly regulated in response to different environmental cues, developmental stages, and cellular needs. This regulation allows for specific genes to be turned on or off as needed for the organism's survival and functioning.
What does recessive albinism mean?
An Autosomal recessive pattern is one in which certain genes of the X sex chromosome are turned off, autosomal is in reference to the X chromosome and the fact that the genes are turned off is indicated by the recessive. So in the case of Albinism the pigmentation genes in the X chromosome are turned off causing the various side effects.
Genes located in different regions of the body during embryonic development may be what?
turned on and off
Why does it take only a few homeotic genes to control the development of a eukaryote?
Different genes are turned on or off in the different cell types as a result of specialization
What turns the lac operon on and off?

This leads to the activation of the lac repressor protein, allowing the expression of genes involved in lactose metabolism. The lac operon is turned off when lactose is absent or glucose is abundant, which prevents the unnecessary expression of these genes.
What is the control center of a unicellular organsism?
A unicellular organism is an animal with just one cell, inside the nucleus, there are chromosomes which contain genes, at first all of the genes are turned on (Have a positive charge) ... Depending on which genes are turned off (Had an electron added to them) after the cell was created, this determines the actions of the cell throughout its life... When the genes have been switched off it is then the nucleus which drives the cell to act correctly according to the genetic instructions given by the genes.
What causes weakness in offspring of genetically similar parents?
It's all genetics, genetics are like light switches, some may be turned on which will be the dominant genes and others will be turned off. So the parent that has a weakness' genes will be the dominant genes so the offspring will therefore be weak or have the same/similar weaknesses.
