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.

∙ 14y agoIn theory, yes. All cells of an organism came from one cell (the fertilized egg in the womb), so as long as there were no errors in replication then every cell will have identical DNA. That being said, different cells utilize different portions of that DNA; this is how we have specialized tissue i.e. brain, heart muscle, liver cells, etc. So while the DNA information is identical, the liver cell will transcribe and translate different parts of the DNA than a brain cell would.

How do cells know to develop within a multicellular organism?
They receive instructions in their 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.
Do different types off cells have different DNA?
they are both found in many types of cells
Why is DNA important to the cell?
DNA is the blueprint for cells. Used to reproduce for both single cell organisms and multicell orgainisms. In multi cell orgainisms, DNA is used to determine how the organism will turn out. DNA makes every organism unique. Every cell has the same DNA. The information provided by DNA tells cells what to do. It is responsible for the cells' functions.
In eukaryotic cells DNA has the appearance of a?
It's the same as a prokaryotic organism, a double helix.
What is true of the various types of cells found in an individual multicellular organism?
The majority of the cells have the same DNA is a true statement about the various types of cells found in an individual multicellular organism. Different genes are expressed in different cells is another true statement.
How do cells know to develop within a multicellular organism?
They receive instructions in their DNA.
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.
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.
Where is a multicellular organism DNA located?
in the cell membrane
Where is DNA located in a multicellular organism?
in the cell membrane
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 different types off cells have different DNA?
they are both found in many types of cells
What is the difference between singled-cell and multicellular organisms?
Multicellular organisms tend to have a higher level of specialization. For example, the cells in your eye share have same DNA as the ones in your muscles, but they serve very different functions. While a multicellular organism forms, identical cells are separated into different organs. They develop specialized organelles and connections so they can do specific jobs.
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.
