Yes, with one exception. Each of an organism's somatic (body) cells contain a complete copy of the hereditary material DNA, arranged in two sets of chromosomes. The sex cells, however, contain only one set of chromosomes.

∙ 10y agoNo. This is because of the extreme diversity in all life and as should be expected, humans have a lot more DNA (# of base pairs, codons) than say E.coli. Even members of the same species have slight variances in this number due to their separate lines of lineages and the heritable mutations associated. Ideally, every cell in a single multicellular organism, save for gametes, should have the same amount of DNA, however, this is not definitive due to point mutations in each individual cell, so even on this level there will be variances. However, complexity of an organism does not correlate with more DNA every time. Take for instance Daphnia pulex, a tiny aquatic crustacean, has many more genes than even Humans. in other words, it all really depends on our evolutionary trajectory.

Is your mouth and finger DNA the same?
All cells have DNA in them. If you take cells from your mouth and finger they would have the same genetic code.
Is the DNA in people's cheek cells as the same as the DNA in other cells?
Yes. Within a single person, all of the somatic cells have the same nuclear genomic DNA; it does not matter if you compare DNA from a cheek cell to a liver cell.
What cells would I use to extract DNA from a living person?
Any cells can be used as you will find DNA in almost all of them (a few exceptions are red blood cells, platelets, etc.) but even where one specific cell in a tissue has no DNA many adjacent cells in the sample will have DNA.
What percentage of thymus cells contain DNA?
All cells contain DNA (even cells with no nuclei have mithcondria which encode their own genome). thymus cells have an especially high amount of DNA since they serve as a place where T cells mature.
Is your DNA in your brain the same as the DNA in your skin cells why or why not?
DNA is the genetic blueprint to make your body function. All DNA is identical throughout your body.
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.
Do all somatic cells contain the same amount of DNA?
yes all somatic bady cells have the same genetic make up except lymphocyets.
Is your mouth and finger DNA the same?
All cells have DNA in them. If you take cells from your mouth and finger they would have the same genetic code.
Is iit true or false that our sex cells have the same amount of dna in as your heart cells?
That is false. All body cells, including heart muscle cells have 46 chromosomes. Sex cells have 23 chromosomes.
Is the DNA in people's cheek cells as the same as the DNA in other cells?
Yes. Within a single person, all of the somatic cells have the same nuclear genomic DNA; it does not matter if you compare DNA from a cheek cell to a liver cell.

Any cells can be used as you will find DNA in almost all of them (a few exceptions are red blood cells, platelets, etc.) but even where one specific cell in a tissue has no DNA many adjacent cells in the sample will have DNA.
What do all cells taken from the same organism have?
The same genetic code or DNA.
Is it true that a cell's size increases its amount of DNA also increases?
Yes, The larger a cell becomes, the more demands the cell places on its DNA. In addition, a larger cell is less efficient in moving nutrients and waste materials across the cell membrane. Hope this helped! (:
Does the chromosomal number change at all during mitosis?
No. Mitosis produces identical daughter cells - same DNA and same amount. Only in meiosis does the chromosome number halve.
Would the DNA be the same in any cell in the human body?
Yes, (except for slight random replication mutations that may happen due to exposure to radiation or harsh chemicals or invasion by viruses) apart form the egg and sperm cells which contain only half the DNA.
What if your skin cells have the exact same DNA as your blood cells?
This would be normal. All body cells have the same DNA, including blood cells, at least at some point during their life cycles. Mature red blood cells do not contain DNA because they do not have cell nuclei. But when red blood cells are first formed, they do have a nucleus with DNA identical to the rest of the body cells.
How is dna hereditary material?
DNA are the "instructions" for cells which contain all the genetic material. When a cell divides, the DNA inside its nucleus replicates and forms the same DNA strands in the two new cells. Therefore, when cells divide by meiosis to form sex cells, they contain the same codes of DNA as the cell they divided from, giving them hereditary characteristics.
