The new DNA molecule is identical to the original DNA.
Hope this helps! :)
Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
That's how you know the age of fossils hope this helps diamonds in the name
