All of the mitochondria in a person's cells originally came from the person's mother in the original egg cell. Mitochondria have their own DNA which they replicate before reproducing. The father's sperm cell that fertilized the egg does not contribute any mitochondria to the zygote formed from fertilization. Therefore, mitochondrial DNA comes only from a person's mother.
What else can I help you with?
If the DNA of the mother is A and the child is A pos what is the DNA of the father?
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
Is the function of cytoskeleton contain DNA?
No cytoskeleton is made up of proteins.It does not contain DNA.
Is there anything that does not contain DNA?
Yes. Anything that isn't an organism will not contain DNA. For example, rocks do not have DNA. Additionally, some viruses have RNA instead of DNA although viruses would be covered by the first category mentioned.
Give an example of the virus that contain DNA as its genetic material?
The virus for warts and chickenpox's contain DNA.
Do mitrochondria contain DNA?
Yes, but mitichondrial DNA is passed directly from the mother, because sperm contain very few organelles to make them more streamlined and likelier to reach the egg, so the mitchondria only resides in the cytoplasm of the egg, making everyone's mitochondrial DNA an exact copy of their mothers. Mitochondrial DNA typical resides longer in bones, making it easier to trace through history.
What happens to the fathers mt DNA?
It does not get passed down to the offspring. Only that of the mother does.
What organelle can be found in DNA?
i think its in the nucleus
If the DNA of the mother is A and the child is A pos what is the DNA of the father?
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
How does a blood test connect two siblings with a the same mother?
A DNA sample is extracted from a swab taken from the mouth of each sibling. The resultant DNA 'fingerprints' are compared to a sample fingerprint of the mother's DNA. They should contain half the DNA fingerprint of the birth mother.
Which organelle contains all of your DNA or your entire genetic make-up?
The nucleus. Mitochondria also contain DNA, but not your whole genome. Your mitochondrial DNA comes only from your mother.
Does DNA contain potassium?
No, DNA does not contain potassium.
Does DNA contain 23 chromosomes?
No. DNA doesn't contain chromosomes. Chromosomes are DNA.
Does water contain DNA?
No, water does not contain DNA. DNA is a molecule found in the cells of living organisms, not in water.
What if DNA does not match mothers DNA?
If it does not match, than it is not that persons child.... adoption... or carrying another womans eggs On very RARE occasions a person can be chimeric... and they "Are there own twin" Basically they contain the cells, and therefor DNA for 2 different people... if the DNA making up the uterus and ovaries is not the same as the DNA used for testing, as it usually is not, then the results will show that the mother is not the mother.
Is the function of cytoskeleton contain DNA?
No cytoskeleton is made up of proteins.It does not contain DNA.
Why don't fathers pass on mitochondrial DNA to their offspring?
Fathers do not pass on mitochondrial DNA to their offspring because mitochondria, which contain the DNA, are only inherited from the mother's egg cell. Sperm cells do not contribute mitochondria to the offspring during fertilization.
Is there anything that does not contain DNA?
Yes. Anything that isn't an organism will not contain DNA. For example, rocks do not have DNA. Additionally, some viruses have RNA instead of DNA although viruses would be covered by the first category mentioned.
