If the cells are part of the same organism, then no, they don't contain different genes. This is a common misconception - although the two cells have very different functions, they have the exact same DNA. The difference is due to the way the DNA is transcribed and translated. Genes that function as enzymes in the liver will be present in the DNA of a kidney cell, but it won't be expressed into the polypeptide.
There are a variety of factors that may "turn off" a gene, some of which include histone acetylation and DNA methylation. If nucleosomes in a chromosome are not acetylated, then they will be more condensed into one area. This in turn may block the RNA polymerase from attaching to a promoter sequence and transcribing the gene. Similarly, methyl groups can bond to the gene, blocking RNA polymerase. This ensures that genes that usually function in different organs aren't expressed.

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.
Do all body cells activate the same genes?
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.
For what molecule do genes contain the intructions for building?
Different genes contain the information to construct different proteins which lead to the formation of different cell type and thus the organism.
What is the difference between Cells and Genes?
Cells are the basic structural and functional units of living organisms, containing all the necessary components for life. Genes, on the other hand, are segments of DNA that contain instructions for building proteins and determining traits. Genes are found within cells and are passed down from parents to offspring.
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?
Does a cell in your stomach contain genes for brain cells?
No, a cell in your stomach does not contain genes for brain cells. Different types of cells express different sets of genes to carry out their specific functions in the body. Brain cells and stomach cells have different gene expression profiles to support their distinct roles in the body.
What do egg cells usually contain?
genes
What do chromosomes contain that control the characteristic of the cells?
genes
Does a cheek cell contain the same chromosomes as a liver cell?
Yes. In an individual, almost all cells contain DNA (Red Blood Cells do not). That DNA is tightly wound like you would twist a drawstring, and kept tightly coiled as chromosomes. Since chromosomes can be found in a cheek cell, a liver cell (hepatocyte), and almost all other cells, they all contain the same chromosomes, which inevitably have the same genes. What makes cheek cells different from liver cells is which genes are turned on and off. Cheek cells have different genes turned on compared to liver cells.
Do body cells contain a complete set of genes?
Yes, they do.
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.
What are threadlike structures in nucleus of cells that contain genes?
DNA, deoxyribonucleic acid, is the structure that contains the genes.
Does The nucleus of a cell in your thigh muscle contains the same genes as the nucleus of a cell in your brain?
Yes, the nucleus of a cell in your thigh muscle and the nucleus of a cell in your brain both contain the same set of genes. However, different genes are activated in different types of cells, leading to the development of specialized muscle or brain cells with distinct functions.
Do all body cells activate the same genes?
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.
Do different kinds of cells in an embryo have different sets of genes?
No. With the odd exception (eg. mature red blood cells because they have no nucleus) every cell in a multicellular organism has the same set of genes. What gives the cells their different character, their phenotype, is which of these genes are expressed at any given time.
For what molecule do genes contain the intructions for building?
Different genes contain the information to construct different proteins which lead to the formation of different cell type and thus the organism.
Do tumor viruses contain genes that are found in normal cells?
not in all cases, however, but yes
