Yes, you do. *
The reason is that all your somatic (body) cells are descended from just one cell: the zygote (fertilized egg). Because your body cells have all been formed by mitosis, they are genetically identical. Exceptions: Gametes (ova, or unfertilized eggs, and sperms) are formed by a different kind of division, meiosis. They have only one set of chromosomes, whereas your body cells have two sets. Over a human lifetime, occasional mutations may occur randomly in the genome and randomly in the body.

∙ 13y agoGreat question! This question is still under scientific debate. You are right that they all contain the same DNA. The answer is complicated, but the short version is that not every gene that is encoded by the DNA is expressed in every cell.
Each specialized type of cell also expresses a tissue-specific set of genes, which are unique to that particular tissue or organ. Kidney cells express a set of kidney-specific genes, while bone cells express a set of bone-specific genes.
The cells become specialized for a particular function during the development of the organism.
We think of different organs and characteristics as traits or features but as far as cells are concerned all of these tissues etc have a function (eg. your hair forms because thousands of years ago we were covered in fur for warmth and protection).

Are DNA in muscle and skin the same?
DNA is found in two organelles: the nucleus and the mitochondria. The amount of nuclear DNA is fixed and does not vary from cell to cell, but the number of mitochondria can affect the amount of mitochondrial DNA.
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."
Does replication provide a means for passing DNA from cell to cell and organism to organism?
Yes all DNA and genetic info is passed from cell to cell when the original cell divides producing 2 daughter cells. The daughter cells have exactly the same DNA and genetic info as the Parent Cell. This the only way that DNA can be passed from cell to cell.
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,
Do all cells contain dna and rna?
yes Some have 70s ribosmes,some 80s. DNA is found same in every organism
What do all cells taken from the same organism have?
The same genetic code or DNA.
Does the DNA in the skin cell have the same sequence of bases as the DNA in the brain cell of the same organism?
It is true thatÊthe DNA in the skin cell have the same sequence of bases as the DNA in the brain cell of the same organism. The sequence of the bases should be the same in all cells of an organism.
Do all cells within an individual carry the same assortment of DNA?
Every cell within an organism contains the same DNA. In higher organism, this DNA is selectively expressed. Genes are turned on and off depending on the cell.
What should be identical for every cell in the body?
the DNA should be the same in all cells as long as they part of the same organism.
Are DNA in muscle and skin the same?
DNA is found in two organelles: the nucleus and the mitochondria. The amount of nuclear DNA is fixed and does not vary from cell to cell, but the number of mitochondria can affect the amount of mitochondrial DNA.
The genetic information of a living organism is located in the organism's .?

Are all cell the same in a multicellular organism?
Almost all cells in a multicellular organism are genetically the same - i.e. they have identical DNA. However, through a process called "differentiation", cells diverge in size, shape, and function by having different sets of genes turned off or on.
Why mitochonria have their own DNA?
Mitochondria is suspected to have been a unicellular organism that invaded cells. All cells have DNA. The mitochondria then stayed in the cells which explains why there are mitochondria in cells now.

Why do mitochondria and chloraplasts contain DNA?
because all cells in a living organism contain the DNA no matter what type of cell it is.
