Every cell in the entire organism contains all the DNA that the original zygote had. The genes that the specialized cells don't use are inactivated.
In 2006, Shinya Yamanaka made a groundbreaking discovery. He found a new way to reprogrammed adult, specialized cells to turn them into stem cells. These laboratory-grown stem cells are pluripotent- they can make any type of cell in the body - and are called induced pluripotent stem cells, or iPS cells.
Only embryonic stem cells are naturally pluripotent. Yamanaka's discovery means that theoretically any dividing cell of the body can now be turned into a pluripotent stem cell.
What else can I help you with?
Is the DNA in prokaryotic cells circular or eukaryotic cells?
The DNA in prokaryotic cells is circular, while the DNA in eukaryotic cells is linear.
Why do all cells need DNA?
DNA is a set of instructions for proteins and proteins are the building blocks of your body.If some DNA is missing or not in the right order (a mutation) a protein may be made wrong or not made at all.That protein could be very important such as insulin which leads to diabetes or a protein receptor on a cell may be the wrong shape like in cystic fibrosis.These mutations are not totally disasterous, however a big chunk of DNA gone missing will most likely result in that embryo not surviving.
How do embryonic cells become differentiated?
Embryonic cells start off as stem cells in the body, and you have a ton of them when you are born. When they go through Meiosis and Mitosis, they soon become differentiated because they are soon assigned certain jobs in the body. So a stem cell has no specific function in the body, but when it becomes differentiated, they receive a certain function. I'm not specifically sure how they BECOME differentiated, but I do know that they do go through Meiosis and Mitosis........hope that helps a bit. A: The Above plus: - Embryonic cells become differentiated mainly with highly-controlled modifications known as Gene Expression. The DNA in the embryonic cells will differentiate as the following: 1) Transcription 2) RNA Processing 3) Non-coding RNA Maturation 4) RNA Export 5) Translation 6) Folding 7) Protein Transport (Need More Information)
Is it true or false that prokaryotic cells contain more DNA than eukaryotic cells?
False. Eukaryotic cells generally contain more DNA than prokaryotic cells. Eukaryotic cells have their DNA enclosed within a nucleus, whereas prokaryotic cells have their DNA located in the cytoplasm.
What cell have DNA inside the nucleus?
the anwer is anmal cells or short i dont know the technical name right off the top of my head
What organisms have eukaryotes?
Prokaryotic cells dont have a nucleus but have DNA.
Cells whose DNA is held in a nucleus are what?
I dont know
In the movie Jurassic Park did scientists use dna to bring back extinct species how is that different from the creation of cloned sheep used differentiated cells?
Yes they used the dinosaur DNA from fossilized mosquetos and the DNA from a toad, I think
What organism is eukaryotic?
There are too types. Prokaryotes and Eukaryotes. Prokaryotic cells dont have a nucleus but have DNA. Eukaryotic cells have a nucleus enclosed by a membrane. The nucleus hold the cells DNA.
Why do you have DNA in your cells?
You have DNA in your cell because you need DNA to be some one and you should have DNA in your nucleus
When do cells need to copy their DNA?
because it need to form then them
What things that a researcher should avoid?
genes are the cells in DNA but i dont know what a chromosone is
What do red blood cells need for DNA syntheses?
oxygen
What do cells need to do before they undergo mitosis?
Replication of DNA

What does a cell of a eukaryote have to hold DNA that a cell of a prokaryote does not have?
DNA in prokaryotic cells is usually circular while DNA in eukaryotes is usually linear. DNA in prokaryotes usually has fewer portions that dont code for something while eukaryotes usually have quite a bit of DNA sections that dont code for anything. The number of actual base pairs (the units that makeup DNA) that makeup eukaryotes is usually quite a bit more than the number in prokaryotic DNA.
Why do cells need to be sure and receive an exact copy of DNA?
munchies
