DNA from the Beginning - An animated primer of 75 experiments that made modern genetics. Deliberate releases and placing on the EU market of Genetically Modified Organisms Genetics | Learn Science at Scitable Half of your DNA is determined by your mother's side, and half is by your father. So, say, if you seem to look exactly like your mother, and had gotten all phenotypes from her, perhaps some DNA that codes for your body and how your organs run was copied from your father's genetic makeup. So close, yet so far. In fact, it is through this dynamic regulation of gene expression that organismal complexity is determined. Additional examination of different organisms has revealed that all genomes are more complex and dynamic than previously thought. Detailed comparative analysis of different organisms' genomes has also shed light on the genetics of evolutionary history. Within a population, beneficial alleles are typically maintained through positive natural selection, while alleles that compromise fitness are often removed via negative selection. Our understanding in all these fields has blossomed in recent years.
Kentucky Blues The story of an Appalachian malady, an inquisitive doctor, and a paradoxical cure. by Cathy Trost ©Science 82, November, 1982 Six generations after a French orphan named Martin Fugate settled on the banks of eastern 's Troublesome Creek with his redheaded American bride, his great-great-great great grandson was born in a modern hospital not far from where the creek still runs. The boy inherited his father's lankiness and his mother's slightly nasal way of speaking. What he got from Martin Fugate was dark blue skin. Doctors were so astonished by the color of Benjy Stacy's skin that they raced him by ambulance from the maternity ward in the hospital near Hazard to a medical clinic in . A transfusion was being prepared when Benjy's grandmother spoke up. "My grandmother Luna on my dad's side was a blue Fugate. Benjy lost his blue tint within a few weeks, and now he is about as normal looking a seven-year-old boy as you could hope to find. Cawein is no stranger to eccentricities of the body.
Bananflugespel Du har säkert irriterat dig på den lilla bananflugan som brukar hålla till runt övermogen frukt. Vad du kanske inte visste är att just den flugan bidragit till mängder av kunskap om våra gener. Den amerikanske forskaren Thomas Hunt Morgan, kunde år 1910 med hjälp av bananflugan bevisa att det var kromosomerna som bar på generna. För detta blev han belönad med Nobelpriset i medicin. I det ca 10 minuter långa kunskapsspelet Bananflugan - "Dating & Mating" får du lära känna bananflugan lite närmare! När spelet är slut kan du skicka in förslag på "raggningsrepliker" mellan en bananflugehane och -hona. Innan du spelar kan du läsa "Kort om bananflugan" så får du förmodligen ett bättre resultat!
