What is the DNA damage theory of ageing?

Q: What is the DNA damage theory of ageing?

A: The DNA damage theory of ageing is the understanding that ageing occurs as a result of damage to DNA in an individual.

Q: What accumulates, even though there are cell mechanisms that repair most of the damage?

A: Damage accumulates (builds up) in an individual's DNA.

Q: Is it only mitochondrial DNA that may have DNA damage?

A: No, both mitochondrial and cell nucleus DNA may have DNA damage.

Q: Which type of DNA is the main subject of analysis regarding the DNA damage theory of ageing?

A: Nuclear DNA is the main subject of analysis.

Q: What is the result of DNA damage over time?

A: The result of DNA damage over time is ageing.

Q: Does the DNA damage theory of ageing propose any other cause of ageing?

A: The DNA damage theory of ageing suggests that ageing primarily occurs due to DNA damage.

Q: Are there any mechanisms that repair DNA damage?

A: Yes, there are cell mechanisms that repair most of the DNA damage.
