Prokaryotic cells use regulatory proteins like repressors or activators that bind to the DNA to turn genes on or off. Eukaryotic cells use a combination of transcription factors, chromatin remodeling complexes, and non-coding RNAs to regulate gene expression.
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.
Small interfering RNA (siRNA) is a non-protein molecule that can result in the ability of the cell to turn off genes. siRNA binds to complementary messenger RNA (mRNA) molecules, leading to their degradation and preventing translation into protein, effectively silencing gene expression.
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.
No, life activities do not directly change genes. However, environmental factors and lifestyle choices can influence gene expression through a process called epigenetics, where external factors can turn genes on or off without altering the underlying DNA sequence.
No, an organisms' genes cannot 'turn off' at any point. They are not mechanical in any way.
A lac repressor turns off the lac genes by binding to the operator.
it likes chicken then not its like turning it off and on
Yes, genes can turn on and off in a process called gene regulation. Factors that influence this process include environmental cues, cellular signals, and regulatory proteins.
Clever mechanisms turn genes off and on so that they only function when there is a need for their services
DNA Manipulation
Well to start off grey hair can be cause by alot of thing such as age and stress. So to answer your question yes stress can cause grey hair.
The function of DNA in a cell is to code the way proteins turn genes on or off, and to carry genetic material.

It depends what the parents genes are.
