Damage in mitochondrial DNA can have the most effect on cellular energy production. Mitochondria are responsible for generating ATP through oxidative phosphorylation, and any damage to their DNA can lead to a decrease in energy production, affecting various cellular functions and potentially causing cell dysfunction or death.

Explain two ways mitochondria may be involved with aging?
Mitochondria play a crucial role in producing energy for the cell through oxidative phosphorylation. Over time, accumulated damage to mitochondrial DNA can lead to decreased energy production and increased production of reactive oxygen species, contributing to cellular aging. Mitochondria are also involved in regulating cell death (apoptosis). As cells age, mitochondrial dysfunction can disrupt this process, leading to the accumulation of damaged and dysfunctional cells, which can contribute to tissue aging and age-related diseases.
Where is DNA found in the eukryote cell?
There are two kinds of DNA in a eukaryotic cell, nuclear and mitochondrial. Nuclear is found in the nucleus and mitochondrial is found in the mitochondria. However, not as many people know about mitochondrial DNA and the only time it is ever refered to is when you are tracking the mother's side of a family with DNA. So for the most part, DNA is found in the nucleus.Eukaryote DNA is located in the nucleus of the cell.
What do mitochondria have that most other organelle dont have?
Mitochondria have their own DNA, known as mitochondrial DNA, which is separate from the DNA found in the cell nucleus. This unique feature allows mitochondria to replicate independently of the cell division cycle.
Who discovered mitochondrial DNAprofiling?
Mitochondrial DNA profiling was developed by Dr. Alec Jeffreys in the 1980s. He is also known for pioneering DNA fingerprinting techniques.
Do mitrochondria contain DNA?
Yes, mitochondria contain their own DNA, known as mitochondrial DNA (mtDNA). Mitochondrial DNA is separate from the DNA found in the cell's nucleus and is responsible for encoding some of the proteins needed for mitochondrial function.
Where do you get your mitochondrial DNA from?
In most organisms, including humans, the mitochondrial DNA is inherited from the mother.
The discovery of mitochondrial DNA (mtDNA) had no effect on which area of scientific investigation?
The discovery of mitochondrial DNA (mtDNA) did not have a significant impact on the field of nuclear DNA research, as they are separate and distinct areas of investigation. Mitochondrial DNA is mainly used for studying maternal ancestry and evolutionary relationships within populations.
When was Mitochondrial DNA - journal - created?
Mitochondrial DNA - journal - was created in 1980.
Who shares your mitochondrial DNA?
Mitochondrial DNA comes from the mother, so the mother's maternal line and all her children share the same mitochondrial DNA.
What does mitochondrial DNA code for?
Mitochondrial DNA codes for certain proteins that are essential for the function of the mitochondria, the cell's powerhouse. It also contains genes involved in energy production through oxidative phosphorylation. Mitochondrial DNA is separate from the nuclear DNA and is passed down maternally.
Which is larger Human mitochondrial DNA or yeast mitochondrial DNA?
Yeast's is (~78kb), while human's is about 17kb
How does the inheritance of mitochondrial DNA different found in the nucleus of cells?
Mitochondrial DNA is only inherited from the mother, while nuclear DNA is inherited from both parents. Mitochondrial DNA is circular and does not undergo recombination, whereas nuclear DNA is linear and can recombine during meiosis. Mitochondrial DNA codes for a small number of genes related to energy production, while nuclear DNA contains genes that determine various traits and characteristics.

Mitochondrial DNA is replicated independently from nuclear DNA?
Yes

Is it true that soda can alter DNA test?
Drinking soda will not alter your DNA on a test that tests chromosomes, such as DNA tests that test the risk of your offspring having certain inherited diseases. Sodium benzoate, an additive that studies have linked to mitochondrial DNA damage related to cirrhosis of the liver, is no longer used in most sodas.
