Human genome
The human genome consists of 23 chromosome and the small mitochondrial DNA. 22 of the 23 chromosomes are autosomal chromosome pairs and the last one being a gender-determining pair. In total, the human genome contains the sequences of the 3 billion chemical base pairs that make up human DNA and approximately 20,000-25,000 genes. By understanding human genome, scientists are able to develop new medical applications that can significantly advance the state of health care.
