What is gene silencing?
When a gene is "turned off", usually by a newish discovery called miRNA.
What is an allele whose trait always shows up in the organism?
type 2 Diabetes
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 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]).
Do The actions of DNA binding proteins help to determine whether a gene is turned on or off?
No, that is false. according to prentice hall biology book chapter 12 section 5
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 off?
How is a gene not expressed
What is gene silencing?
When a gene is "turned off", usually by a newish discovery called miRNA.
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 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 is an allele whose trait always shows up in the organism?
type 2 Diabetes
What is an example of a signal molecule that can bind to an intracellular receptor and thereby cause a gene to be turned on or off?
steroid
What is an example of a signal molecule that can bind to an intracelluar receptor and therby cause a gene to be turned on or off?
steroid
What does the term get off mean?
get off on it is slang for Get turned on by something.
Why do organisms turn on and off genes?
Each cell in out body contains all the genetic information of that organism. However, not all the information is needed. For example, a muscle cell only needs information about being a muscle cell so it would turn off information/ genes that it does not need. Also, some genes can be turned on and off when needed. For example, some bacteria can use lactose but lactose is not always present in the environment. Instead of wasting time making lactose enzymes, the bacteria would keep the gene turned off until it was needed.
When referring to storage media what does volatility mean?
It generally means storage that is temporary. Often that is expressed by the data disappearing when the computer is turned off. A less volatile medium, such as a hard drive, would keep data even while off.
