What do prokaryotic and eukaryotic cells use to turn certain genes on or off?
Proteins
What non protein molecule would result in the ability of the cell to turn off genes?
corepressor
What is the term for genetic markers that turn DNA segments on and off?
The epigenome refers to the markers that turn on and off specific genes. The markers themselves are named according to their chemical composition, ie. methyl-markers.
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.
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.
Can your genes turn on and off?
No, an organisms' genes cannot 'turn off' at any point. They are not mechanical in any way.
How can scientists alter genes?
By introducing chemicals into the area that (thing) that they want to alter the genes of, they can "turn off" or "turn on" different genes that were dormant or active, but pre-existed in the subject
What causes the lac genes in E. coli to turn off?
A lac repressor turns off the lac genes by binding to the operator.
How do prokaryotic cells turn genes on and off?
it likes chicken then not its like turning it off and on

How do dna-binding proteins in prokaryotes regulate genes?
Clever mechanisms turn genes off and on so that they only function when there is a need for their services
What non protein molecule would result in the ability of the cell to turn off genes?

Scientists are trying to find a way to turn off the genes that cause genetic disease This would be a type of?
DNA Manipulation
Does dying your hair cause grey hairs?
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.
What is the function of DNA a cell?
The function of DNA in a cell is to code the way proteins turn genes on or off, and to carry genetic material.
