Can you repair damaged DNA?
Most damage to DNA is repaired by removal of the damaged bases followed by resynthesis of the excised region. Some lesions in DNA, however, can be repaired by direct reversal of the damage, which may be a more efficient way of dealing with specific types of DNA damage that occur frequently.
What happens to a cell whose DNA damage is so severe that it Cannot be repaired?
At the cellular level, damaged DNA that is not properly repaired can lead to genomic instability, apoptosis, or senescence, which can greatly affect the organism’s development and ageing process.
What can happen if DNA becomes damaged?
The DNA in just one of your cells gets damaged tens of thousands of times per day.

Does both parents have to be swabbed for a DNA test?
Even though the standard home paternity test kit includes DNA swabs for the mother, father, and the child, it is not required to have the mother’s DNA. A child inherits their DNA from their mother and their father equally. Without DNA from the mother, the child’s DNA can only be compared to the DNA from the father.
