Is an expressed gene turned off?
No. If a gene is expressed, it is turned on.
What does it mean for a gene to be turned off or not expressed?
When a gene is turned off or not expressed, it means that the DNA sequence within that gene is not being transcribed into mRNA and translated into protein. This can happen through a variety of mechanisms that regulate gene expression, such as DNA methylation, histone modification, and transcription factor binding.
What is an AADL Arabidopsis?
It is an arabidopsis plant with the AADL protein "turned off." Scientists insert a nucleotide into the gene sequence which stops the AADL gene from being able to function. The AADL gene tells a ribosome to make the AADL protein. With it being turned off, the AADL protein never gets made.
What if your O gene on your X chromosome can be thought of as a switch that is either on making you orange or off making you black What are you?
If the O gene on your X chromosome acts as a switch, with "on" making you orange and "off" making you black, you would be a female since the gene is located on the X chromosome. In this scenario, if you had the O gene turned on, you would have orange fur or skin, and if it was turned off, you would have black fur or skin.
What does it mean when a gene is "turned off" in terms of genetic expression?
When a gene is "turned off" in terms of genetic expression, it means that the gene is not being actively used to produce proteins or other molecules in the cell. This can happen through a variety of mechanisms that prevent the gene from being transcribed into messenger RNA, which is needed for protein synthesis. As a result, the function of the gene is temporarily or permanently silenced, leading to a decrease or absence of the corresponding protein or molecule in the cell.
Do The actions of DNA binding proteins help to determine whether a gene is turned on or off?
Yes, DNA binding proteins can influence gene expression by binding to specific sites on the DNA and either promoting or inhibiting gene transcription. These proteins can act as activators to enhance gene expression or repressors to suppress gene expression, thus controlling whether a gene is turned on or off.
What are genes that are turned off called?
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.
What gene causes lupus?
it has been suggested that DNase1, part of the "junk" DNA in the nucleus, is responsible. I recall an experiment with mice where this gene was turned off and mice started presenting with signs of SLE.
How are genes turned on and off in a cell?
Each cells in our body expresses. That means turning ON only the part of its genes. The rest of the part are usually repressed (i.e turned off). The process of gene turning ON and OFF is called as gene regulation. And it is one of the important part of each cell development and activities. Because this is the stage where each cell in our body is differentiated from others. For example the cardiac cell is different from nephrotic cells, neurons, muscle cells etc. There are various cell factors and environmental factors that affect the gene regulation. The signals from adjacent or other cells activates gene regulation. Gene regulation can happen at any moment during gene expression but usually occurs at the transcription phase (i.e Transforming the DNA into mRNA [Messenger RNA]).
If a specific kind of protein is not continually used by a cell the gene for that protein is?
the gene is never expressed. ^^^^ this guy is a frickin idiot. and this would more of be in the cells/ biology section. What happens is a repressor binds to the operator and turns off the gene so the protein doesn't get made. and when its needed the repressor detaches and the gene is turned back on. ( this all happens on a strand of DNA )
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 is gene silencing?
Gene silencing is a process by which the expression of a specific gene is suppressed, leading to a reduction or elimination of the gene's protein product. This can occur through various mechanisms, such as RNA interference or epigenetic modifications, which can silence gene expression at the transcriptional or post-transcriptional level. Gene silencing plays a crucial role in regulating gene expression and can be used in research and therapeutic applications.
