Caenorhabditis elegans is a species of nematode, commonly referred to as roundworms, that is widely studied by scientists across various fields.

DNA, also known as deoxyribonucleic acid, is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.

Drosophila melanogaster is a species of fruit fly that is commonly used as a model organism in genetic and biomedical research.

Eukaryotes are complex organisms whose cells contain a nucleus and other membrane-bound organelles.

Genome projects are scientific endeavours that ultimately aim to determine the complete genome sequence of an organism (be it an animal, a plant, a fungus, a bacterium, an archaean, a protist or a virus) and to annotate protein-coding genes and other important genome-encoded features.

Homo sapiens is the scientific name for the modern human species.

The Human Genome Project (HGP) was an international scientific research project with a goal to determine the sequence of nucleotide base pairs that make up human DNA, and to identify and map all of the genes of the human genome from both a physical and functional standpoint.

The Human Genome Project (HGP) was an international scientific research project that aimed to map and understand the complete genetic blueprint of a human being.
