All cells have identical DNA ... with the exception of gametes (sperm and egg cells). Gametes have only half the DNA present in a normal cell, though if many gamete cells are present the average DNA profile will be the same as that in a skin cell.

∙ 9y agoI wish it were that simple but the fact that DNA is present doesn't means cells are interchangeable. DNA is only encoded information in the form of protein. It's kept inside the nucleus of the cell and functions to helps in the production of proteins. The rest of the cell is specialized for certain functions.
A stomach cell is very different from a skin cell in terms of makeup and structure (how they form together to make tissue). The only cells that are not specialized for a certain purpose are stem cells. These have not yet taken any special forms and can be converted to many types of cells for many purposes. Unfortunately due to the rarity of these cells in adults it's not feasible to do anything with them.
Cloning is a very involved process and with the degree of randomness inherent in biological systems, a specific outcome can not be guaranteed. Here is a quick insight into the complexity of the situation.
You will need a host to incubate the fetus. The best host is a woman whom has been fertilized invitro. To clone yourself you will need to take your DNA and split it in half by a process called meiosis. Sperm and eggs only carry half of the DNA material so when they join they have both parts. Isolating which parts of the DNA that represent you is the hard part. Implanting the parts in the two halves and combining them by fertilization within the host is another miracle. Even then we can't be certain which traits will come out with a good degree of certainty. If the baby is born it will then need to undergo it's growth as a human being, developing it's own character and so forth.
This is an incredibly over-simplified overview of one such process. I believe they can do this with sheep and vegetables. I hope this answers your questions.

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.
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 a liver cell different from a muscle cell and a muscle cell is different from a fat cell?
DNA is alike in other cells of the body, but depending on the specific cell type, some genes may be turned on or off. this is why a liver cell is different from a muscle cell and a muscle cell is different from a fat cell.
Does all of the cells of a multi-cellular organism have the same DNA?
That is because there are different parts of DNA that become active depending on the functions and positions of different cells. For example, in a liver cell, the part of DNA that codes for the production of Insulin is not active, therefore, a hepatic cell can not produce Insulin. However, in some pancreatic cells that part of DNA is active and therefore these cells are able to produce Insulin. DNA is not fully activated in any cell.
What percent of each nitrogen base occurs in human liver cell DNA?
dude I'm high
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.
Why does a skin cell divide more often than liver cell?
As far as I know, liver cells usually only undergo mitosis if the liver is damaged. You should check a few other sources though.
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.
How does DNA make a muscle cell different from a liver cell?
because a muscle cell is a organ and a DNA just see if its true or not.
Can you extract DNA from a skin cell?
yes u can because skin cellls are something that holds dna
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.
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.
Dna makes what protein in a cell?
DNA does not manufacture specific proteins. It codes for many different proteins that depend upon the cell's function. Liver cells' DNA manufactures different proteins that match the function of the liver. Kidney cells' DNA manufactures different proteins that match the function of the kidneys.
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 grind the liver in a DNA extraction lab?
the purpose of grinding any substance during dna extraction is cell loosening.
Why is a liver cell different from a muscle cell and a muscle cell is different from a fat cell?
DNA is alike in other cells of the body, but depending on the specific cell type, some genes may be turned on or off. this is why a liver cell is different from a muscle cell and a muscle cell is different from a fat cell.
Why does the human liver and heart have the same number of dna bases?
same organism=same dna= same bases :D bc sci 9?
