All body cells have the same genes except for the sex cells (sperm and ova). They do not use the same genes. A muscle cell isn't using the same genes as a nerve cell does. Otherwise the muscle cell and the nerve cell would not be different nor do different things.

∙ 11y agoAll cells in a multicellular organism possess the same genes. However, different cell types express different genes. Indeed, that is what makes the cells different. During development, cells are directed towards particular lineages, each lineage activating particular sets of genes, genes that confer a particular identity on a cell and the appropriate properties.

Do different cells have different genes?
If the cells are from one individual, all will have the same genes except their sex cells which have 1/2 the number. A dog will have different genes from a cat. The genes make the cat different from the dog and human.
Why are some cells brain cells and others skin cells when the DNA is the same?
All body cells have the same DNA. They all play different roles because the brain sends them signals to do so. You can't have them all doing the same thing. Ex: If you only have skin cells, then what cells will make up your heart or liver or bones?
How can cells have the same DNA?
Although all calls have the DNA only some parts of it are turned on different cells (this is called gene expression). Which genes of the DNA are turned on determine the functions and kinds of cell. Even in the same kinds of cell genes can be differently expessed depending on what the cell needs to do at the time. If you have a drink of alcohol for instance a whole bunch of genes turn on in the liver to detoxify the alcohol. When you have meal hundreds of genes in the stomach, intestine and blood stream kick into action to digest the food and send it away for storage or immediate use. Cells have many things that regulate gene expression some things turn genes off or down others turn them up or on. There are factors turn on whole cascades of genes.
Why is all of your DNA in all somatic cells?
Somatic cells are all the cells in an organism's body except for the gametes. Certain somatic cells may have different functions in an organism due to differences in gene expression; which simply mean that somatic cells only use certain parts of the DNA. Therefore, all somatic cells have the same DNA. When these cells develop, they will specialize into certain types of cells depending on which genes will turn "on."
Is the DNA in each cell of a single organism exactly the same?
First of all DNA is not a cell. Second of all if DNA was all the same then we would also be the same in thought, apearance, and function. The only time DNA is the same is when it makes up a multicelled organism (or if a Organism is cloned or for a spieces of unicelluar organisms). This was explained by a seven year old,
Are the genes in daughter cells produced by mitoses the same as or different from the genes in the original cell?
No. Because each daughter cells gets a different pair of chromosomes.

Do all plant cells have same number of genes?
No.
Why does a same body has cell of different cells?
Complex organisms, like animals, organize their body in tissues. Each tissue consists out of cells of the same type. This cells, once having finished to differentiate, just have a couple of genes "on". So they can save energy having all the genes "off" that they don't need. And because different tissues like the brain and the intestine need different genes to function properly, the organisms has many different cell types.

Do a pancreas cell and a skin cell have the same set of chrosomes?
All non-mutated somatic (non-sex cell) cells have the same chromasomes and same genes, within an organism. The difference between the cells is which of the genes are active in it.
What are homogeneous cells?
It means they are essentially the same size, containing the same genes with different alleles.
What is the relationship between genes and cells?
the same relationship as between humans and the universe.

What does it tell us if two genes show the same levels of expression in cancer cells and normal cells?
nice
What is the direct result of a normal cells ability to express only certain genes?
Because the genes that are expressed affect every aspect of the cell, from the look and size of the cell to what chemical actions it can carry out, being able to turn some genes off and others on allows the cells to both respond to their environment and, in the case of multicellular organisms, have different types of cells. If the cells in the human body could not regulate their gene expressions then the cells of the liver would be the exact same as the cells of the heart and they would be the same as every other cell. In this situation complex organisms could not exist as we know them.
