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 does it mean for a gene to be off?
How is a gene not expressed
When a gene or genes which code for units which make up a protein are turned on by?
expressed
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.
How is a non-constituative gene turned off?
repressor proteins block the gene physically and prevent transcription from occurring
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 )
What is the main purpose of gene regulation in eukaryotes?
The main purpose of gene regulation in eukaryotes is to control which genes are turned on or off in response to internal and external signals. This allows for precise control of gene expression, ensuring that the right genes are expressed at the right time and in the right amount for proper cell function and development.
Which parts of a gene are expressed as protein?
Coding sequences of a gene are expressed as protein
An expressed gene is one that what?
a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.
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.
Are genes expressed all the time?
No, genes are not expressed all the time. Gene expression is tightly regulated in response to various internal and external cues. Different genes are turned on or off at specific times and in specific cell types to control various functions in the body.
