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.

How are genes organized in organisms?
Genes are sections of DNA found in chromosomes, which in turn are in the nucleus of each cell in the organism.
What can determine an organisms traits?
Genes are what determine an organisms physical traits.
What do prokaryotic and eukaryotic cells use to turn certain genes on or off?
Proteins
What is the term that identifies the genes present in an organism?
the genes can be called inheritable genes..
What does knowing the sequence of an organisms DNA allow researchers to do?
Knowing the sequence of an organism's DNA allows researchers to study specific genes, to compare them with the genes of other organisms, and to try to discover the functions of different genes and gene combinations.
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.
What causes differentiations of cells in complex organisms like humans?
Switching genes on and off.
How do prokaryotic cells turn genes on and off?
it likes chicken then not its like turning it off and on
What can determine an organisms traits?

What controls traits in organisms?
The traits of an organism are controlled by genes and environment. Genes
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
