Figure 2From: Unraveling genomic variation from next generation sequencing data DNA assembly. DNA assembly: 1st step: The DNA is purified and extracted. 2nd step: DNA is fragmented into smaller pieces. 3rd step: DNA fragment sequencing. 4th step: A computer matches the overlapping parts of the fragments to get a continuous sequence. 5th step: The whole sequence is reassembled. No prior knowledge about the DNA sequence is necessary.Back to article page
