Much of what scientist know about their current scientific knowledge comes from research on various organisms. Following contents describes some model organisms and what scientists have learned from those model organism studies.
Mus Musculus (House Mouse); Immune function, Human disease, X chromosome inactivation and stem cells
Drosophila melanogaster (Fruit Fly);Heredity, Human disease, Animal development and circadian rhythms
Arabidopsis thaliana (Mouse-Ear Cress); Control of gene expression, Genome duplication, Disease resistancei, Response to the environment, Hormones, Circadian rhythms and flowering.
Caenorhabditis elegans (Nematode); Animal development, Apoptosis, Muscle function, Drug development, aging and origin of sex.
Neurospora crassa (Red Bread Mold); Crossing over, One-gene/one-enzyme hypothesis, Circadian rhythms and gene regulation.
Dictyostelium discoideum (Cellular Slime Mold); Cell movement, Cytokinesis, Chemotaxis and cell differentiation
Escherichia coli (Bacteria); DNA is genetic material, DNA replication, Gene regulation, Transgenic technology and gene function
