Figure 1From: Quantitative assessment of mitochondrial DNA copies from whole genome sequencingOverview of human whole genome sequencing. A) The human genome is composed of nuclear DNA and mitochondrial DNA. The nuclear DNA is stored on 23 chromosome pairs and there are multiple copies of small DNA located in mitochondria. B) The reads from the sequencing of human whole genome are mixed with both nuclear DNA and mitochondrial DNA.Back to article page
