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.
What else can I help you with?
How are genes organized in organisms?
Genes are organized in organisms on structures called chromosomes. Chromosomes contain long strands of DNA that are made up of genes. Genes are arranged in a linear fashion along the length of chromosomes, with each gene encoding specific instructions for producing proteins or controlling various traits in the organism.
What is a group of individual organisms that have exactly the same set of genes called?
clone- group of indivdual organisms that have exactly the same genes
What are organisms that have their genes altered called?
These organisms would be called mutants.
Do all organisms have Hox genes?
No, not all organisms have Hox genes. Hox genes are specific to animals with bilateral symmetry and are involved in controlling the body plan and development along the anterior-posterior axis. Other types of organisms, such as plants, fungi, and bacteria, do not possess Hox genes.
Determines an organisms phenotype?
genes and environment
Can your genes turn on and off?
No, an organisms' genes cannot 'turn off' at any point. They are not mechanical in any way.
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
Can genes turn on and off, and if so, what factors influence this process?
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.
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

Do genes code for proteins in living organisms?
Yes, genes contain the instructions for making proteins in living organisms.
What is a group of individual organisms that have exactly the same set of genes called?
clone- group of indivdual organisms that have exactly the same genes
What are an organisms traits called?
genes
How does DNA show relationships between organisms?
it shows genes and different genes
What are organisms that have their genes altered called?
These organisms would be called mutants.
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
