Deoxyribonucleic Acid, more coloquially known as DNA, is a molecule carrying instructions for all known living organisms. In most cases, DNA is right-handed (B-DNA) which is the primary DNA handedness in humans. However it is possibel to have Z-DNA (left-handed) molecules. In 2003, the Human Genome Project was completed after a 13-year international effort to sequence the human genome. To this day, their are still many mysteries about DNA and gene expression in general.
