10 Vestigial Traits You Didn't Know You Had

10 Vestigial Traits You Didn't Know You Had

Twins Every summer, on the first weekend in August, thousands of twins converge on Twinsburg, Ohio, a small town southeast of Cleveland named by identical twin brothers nearly two centuries ago. They come, two by two, for the Twins Days Festival, a three-day marathon of picnics, talent shows, and look-alike contests that has grown into one of the world's largest gatherings of twins. Dave and Don Wolf of Fenton, Michigan, have been coming to the festival for years. "Must be a twins thing," Don says. This afternoon at the festival the brothers have stopped by a research tent sponsored by the FBI, the University of Notre Dame, and West Virginia University. "Although identical twins may look the same to you and me, a digital imaging system can spot minute differences in freckles, skin pores, or the curve of their eyebrows," says Patrick Flynn, a computer scientist from Notre Dame. Because their beards cover half of their faces, the Wolf brothers pose a particular challenge. "I don't hate it.

Extraordinary Adaptation Complete Genomics May Be Worth The Gamble I have been following Complete Genomics (GNOM) for a while now. I've even put it in my list of five favorite stocks. I really like its products; I really like its services, and I really like its CEO, Cliff Reid. By all accounts this is a great little company ready to take off like a rocket. Complete Genomics is an early stage biotech company engaged in human DNA sequencing using proprietary machines, process, and analytics. Sequenom (SQNM) and Amarin (AMRN) are two examples of a developmental stage biotechs that missed their quarterly targets but didn't see their stock price take a dive next day.

Rediscovering Biology - Case Studies: The Genetics of Resistance to HIV Infection This case uses the example of HIV, to explore the relationships between viruses, cells and the immune system, and the role of genes in disease resistance. An animation explains PCR (polymerase chain reaction) and electrophoresis and their practical use as a genetic test. We will see how mutations in an HIV receptor confer relative reslstance to infection. We will find out how often this mutation occurs in the general population, and see data about additional mechanisms of HIV resistance. Before beginning this case study, you may want to review these related materials: • HIV and AIDS Video • HIV and AIDS Online Text • Human Evolution Online Text • Genomics Video • Genomics Online Text

Molecular pathology - Human Molecular Genetics - NCBI Bookshelf Evolution in an RNA world. [Cold Spring Harb Symp Quant Biol. 2009] - PubMed result "Junk DNA" Allowed Us to Survive as a Species Highly infectious viral diseases -including the Plague, yellow fever, measles, smallpox and he Spanish Flu, which killed 50 million people at the end of the First World War, moving from one cell to the next, transforming each new host into a factory that makes even more virus. In this way, one infected cell soon becomes billion -that die when the host dies. Endogenous retroviruses, however, once they infect the DNA of a species they become part of that species: they reside within each of us, carrying a record that goes back millions of years. These viral fragments are fossils that reside within each of us, carrying a record that goes back millions of years. That is until Thierry Heidmann who runs the laboratory at the Institut Gustave Roussy, on the southern edge of Paris, brought one to life. After resurrecting the virus, the team placed it in human cells and found that their creation did indeed insert itself into the DNA of those cells. Posted by Casey Kazan.

The driving force for molecular evolution of translation Genes: The Instruction Manuals for Life A gene is a how-to book for making one product—a protein. Proteins perform most life functions, and make up almost all cellular structures. Genes control everything from hair color to blood sugar by telling cells which proteins to make, how much, when, and where. Genes exist in most cells. Inside genes The term gene, first created by Danish botanist Wilhelm Johannsen in 1909, comes from the Greek word for origin, genos. The number of genes in an organism's complete set of DNA, called a genome, varies from species to species. Each gene has many parts. Each gene helps determine different characteristics of an individual, such as nose shape. Peas in a pod The "Father of Genetics," Gregor Mendel, was an Austrian monk who experimented with plants growing in his monastery. Mendel observed that when he bred plants that had green pea pods with plants that had yellow pea pods, all of the offspring had green pods. Individuals have two copies of each gene, one inherited from each parent. More to it
