<span>mtDNA analysis is the best DNA technology to use. In DNA fingerprinting scientists run a gel electrophoresis of the subject's DNA in order to establish the banding patterns of the DNA fragments. People will always share half of their DNA with a parent. SO half of an individual's banding pattern will match half of their parent's DNA banding pattern. If someone is missing is found then scientists can compare the DNA fingerprint or banding patterns to see what the likelihood is of them being related.</span>
The correct answer is - underwater mountain ranges.
The mid-ocean ridges are actually underwater mountain ranges, which usually are very long, in fact the longest mountain range on Earth is created on the divergent boundary between the Eurasian and North American tectonic plates and between the African and South American tectonic plates. At the divergent tectonic boundaries we have the creation of new crust which rises from the mantle and fills in the gap between the tectonic plates. Because of the big amount of magma and high pressure, very big and long underwater mountain ranges are formed.
