DNA sequencing
sequencing is a man manipulated process whereby a chromosome is made easier to handle by cutting it into small pieces. Then these divided pieces are grafted (joined together) into imitation chromosomes which in turn are implanted into bacteria which replicates them

"Researchers take a short piece of a chromosome and make thousands of incomplete copies, all starting from one end. They attach a fluorescent label to the other end, using different colors for different letters. These fragments are separated according to size, allowing the sequence to be read out. Then the short sequence is strung together to give the chromosome's particular sequence.

Another faster way instead of sequencing adjacent segments of chromosomes is; an entire genome is chopped into little pieces and sequenced. Then, like an intricate puzzle, the random bits are put together by computers that look for overlapping fragments....Some DNA segments somehow prevent the artificial chromosome replicating. As a result, these segments will be missing from the final sequence...one segment of DNA looks like every other, so there is no way to pinpoint where in the mass of repeats it came from." ...New Scientist, May 20, 2000.
