Is DNA found in red blood cells?

Answer 1

The answer is yes and no.

DNA is present in immature erythrocites. It is not present in mature erythrocites that actually carry oxygen in the blood stream. The point that they develop from immature to mature erythrocites is when they eject their nucleus.

Answer 2

Red blood cells have no nucleus, and therefore have no DNA. This is because due to evolution red blood cells need the space to carry more oxygen.

Red blood cells DO NOT HAVE DNA. If they did then at crime scenes you could do DNA fingerprinting just from blood samples but you CANNOT DO THIS.

The proteins they have to carry blood are NOT made by the red blood cells themselves. They are made by the bone marrow, where the red blood cells are made in the first place.

Answer 3

You know, before I actually took some time to look the issue up and find out, I assumed that DNA was in red blood cells. I was wrong. You learn something new each day.

The most correct answer here is that it is found in immature red blood cells, but not in mature red blood cells.

Learn something new everyday.

Answer 4

Mammalian red blood cells do not have a nucleus, so they don't have DNA. Rather, mammals have RNA in their blood cells. In immature red blood cells, RNA forms a mesh around it. However, the red blood cells of birds, reptiles, amphibians, and fish have nuclei, so they have DNA. The exception to this is the slender salamanders, the ones of the genus Batrachoseps. These salamanders mostly live on the West Coast of the US.

Answer 5

DNA is encoded on every one of your body cells. This includes your red blood cells. They use to DNA to know what their job is within the human body. I produces all the things that it needs to function within your body. The instructions are found on the DNA. The same pair of DNA chromosomes are found on all of your cells except for your sex cells. Those only have half the number because they need to pair with the person you're having a child with to create a while cell.

Answer 6

Yes it is. DNA is found in every cell in your body. Fun Fact: If you strung out all the DNA in every cell in your body it would be long enough for seventy trips to the sun and back! But yes, without DNA the cell has no instuctions to follow. Another Fun Fact: Since red blood cells are only used for carrying oxygen from the lungs to the other parts of the body, they transcribe and translate much more of the hemoglobin than in other cells.

Answer 7

No there is no DNA in Red Blood Cells (RBC's) since they lose them when they become mature oxtgen carrying cells! Here is the proof:

"Red blood cells are also known as RBCs or erythrocytes (from Greek erythros for "red" and kytos for "hollow", with cyte nowadays translated as "cell")."

This is proof to your answer, the above only explained what erythrocites were as the word is used in this paragraph:

"Erythrocytes in mammals are anucleate when mature, meaning that they don't have a cell nucleus and thus no DNA. "

Enjoy!

Answer 8

Human RBCs are enucleated; the nucleus is removed during development/maturation of the RBC. Since they don't have a nucleus they don't have chromsomes, so no genomic DNA. However, they do have mitocondrial DNA, but this can't be used for fingerprinting, since it's very small, too small for a larger number of mutations to occur which are useful for DNA fingerprinting. So, every other answer is wrong, there is DNA, but not what you think.

Answer 9

In humans there is no nucleus and no nuclear DNA in a red cell but ALSO there are no mitochondria and no mitochondrial DNA in the red cells.

Answer 10

Yes.

Each person's individual DNA is found in every living tissue in their body. So they can map your DNA from blood, from bones, from bone marrow, from the core of your teeth, skin, your saliva. Even on people who have been dead for a thousand years, they can use bone marrow if any remains and one single hair with the follical still attached can be used to map a person's DNA.

DNA is the program of how to make up you as an individual person.
