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.

Genes that are turned off are called repressed genes. The process of turning genes on or off is called Gene Therapy.

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.


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.


What happens to Genes located in different regions of the body during embryonic development may?

Genes located in different regions of the body are activated or deactivated in a coordinated manner during embryonic development. This process, called gene regulation, ensures that specific genes are expressed in specific cells at specific times, leading to the formation of different cell types and tissues. This controlled gene expression is essential for the proper development and functioning of the organism.


What is a short segment of DNA on a chromosome called?

A segment of DNA is called a gene. All an organism's biological traits are the result of gene coding. Though it was once thought that one gene codes for one trait, it is now understood that a gene may code for more than one trait, and genes may work with other genes to produce a trait. It is also known that genes may be turned on or off, but much more study is needed to understand genes completely. Much of the knowledge we have about genes today is the result of the Human Genome Project.

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.

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.

What is the relationship between genes and the environment?

Genes are regulated through a number of ways. Some can be regulated by the environment you're in. For example, if you're in the sun a lot, genes will get turned on or up to increase the production of skin pigmentation so you get tanned. When you stay out of the sun, the genes turn off and your skin gets lighter.


The stuff of the genes?

Genes are made up of DNA, which carries the instructions for building and maintaining an organism's cells and tissues. They determine an organism's traits and characteristics through the expression of specific proteins. Gene expression is regulated by various mechanisms that control when and where specific genes are turned on or off.
