Genetics Animations
Browse our collection of Flash animations that illustrate how the human genome was sequenced, some of the processes and techniques used in sequencing genomes at the Wellcome Trust Sanger Institute and how the DNA code of the human genome is stored and used in our bodies and cells. Our "For Teachers" section shows how these animations can be used in support of the UK AS and A2 Biology curricula.

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. Peppered Moth Simulation Name:______________________________________________ Objective: Simulate changes in moth population due to pollution and predation, and observe how species can change over time. Introduction: Charles Darwin accumulated a tremendous collection of facts to support the theory of evolution by natural selection. One of his difficulties in demonstrating the theory, however, was the lack of an example of evolution over a short period of time, which could be observed as it was taking place in nature.

Transcription activator-like effectors (TALEs) are a class of naturally occurring DNA binding proteins that can be easily customized to recognize novel DNA sequences.The DNA binding domain of each TALE consists of tandem 34-amino acid repeat modules that can be rearranged according to a simple cipher to target new DNA sequences. DNA - The Double Helix Lists of Nobel Prizes and Laureates DNA - The Double Helix Play the DNA - The Double Helix Game About the game Most living organisms have the same sort of genetic material, DNA, in their cells. DNA contains two strands wrapped around each other in a helix, and these strands are held in place by four chemicals called bases: adenine (A), guanine (G), cytosine (C) and thymine (T).

Acquired traits can be inherited via small RNAs Columbia University Medical Center (CUMC) researchers have found the first direct evidence that an acquired trait can be inherited without any DNA involvement. The findings suggest that Lamarck, whose theory of evolution was eclipsed by Darwin's, may not have been entirely wrong. The study is slated to appear in the Dec. 9 issue of Cell. "In our study, roundworms that developed resistance to a virus were able to pass along that immunity to their progeny for many consecutive generations," reported lead author Oded Rechavi, PhD, associate research scientist in biochemistry and molecular biophysics at CUMC.

DNA . Genetics In the 150 years since Mendel's first experiments, geneticists have discovered that genetic traits usually don't follow simple inheritance patterns. Some traits, like human eye color and stature, are produced by the interplay of many sets of genes; these are known as "polygenic traits." Other traits show a phenomenon called intermediate expression, in which a heterozygous genotype will produce a phenotype that's different from homozygous dominant genotypes. In snapdragons, for example, a homozygous dominant genotype makes red flowers, homozygous recessive makes white flowers, and heterozygous individuals are pink. Team:Freiburg/Project/Golden On this page, we introduce the Golden Gate Standard to the Registry of Standard Biological parts. We explain in detail, how Golden Gate Cloning works and how it can be made compatible with existing standards. Moreover, we provide step-by-step protocols for using this new standard. Introduction Although BioBrick assembly is a powerful tool for the synbio community because it allows standardized and simple construction of complex genetic constructs from basic genetic modules, it is not the best option when it comes to assembling larger numbers of modules in a short period of time. Furthermore, BioBrick assembly leaves scars between assembled parts, which is not optimal for protein fusion constructs.

DNA Extraction from Wheat Germ DNA Extraction from Wheat Germ Objective · To observe the physical and chemical properties of DNA · Understand one process of DNA extraction · Demonstrate proficiency with one technique of DNA extraction · Use research to make a drawing of DNA with labeled parts Color Blind Chart Pattern baldness in men is a sex-influenced trait. It is not an X-linked trait like color blindness and hemophilia. Baldness is an autosomal trait and is apparently influenced by sex hormones after people reach 30 years of age or older. This condition is inherited as a simple Mendelian trait, although the biochemical mechanism is complex. There are other causes for baldness not related to simple Mendelian genetics, such as illness, severe stress, and pulling one's hair out by the roots. In men the gene is dominant, while in women it is recessive.

Serious Games Bring Immersive Astronomy To Science Classrooms Serious Games for a high tech space-simulation experience Via: Edutopia - Virtual Universe: Students Use Technology to Reach for the Stars by Bilen Mesfin Full Article Remote telescopes, desktop planetariums, and 3-D space-simulation programs launch classrooms into space Animated Blood Types Since Rh negative people may produce anti-Rh antibodies, Rh positive blood should not be given to an Rh negative recipient. Based upon the above table, Rh positive recipients can theoretically receive positive or negative blood, and Rh negative donors can theoretically give to Rh positive and Rh negative recipients. Therefore, the "universal donor" is O Negative, while the "universal recipient" is AB Positive.

The twisting tale of DNA - Judith Hauck Deoxyribonucleic acid, or DNA, is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses). which contains the biological instructions that make each species unique, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction. National Human Genome Research Institute began as the National Center for Human Genome Research (NCHGR), which was established in 1989 to carry out the role of the National Institutes of Health (NIH) in the International Human Genome Project (HGP). The HGP was developed in collaboration with the United States Department of Energy and begun in 1990 to map the human genome. information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.

Quick Trait Calculator - Genetic Heredity Calculator Note These calculators use simplified models to calculate traits and their certainty is far from 100% due to the fact that human genetics is far more complex than a simple mendelian dominant/recessive model. Personal Report and Heredity Report give better results, providing that you had your genome sequenced by a commercial personal genomics companies like 23andMe, deCODEMe or Family Tree DNA. In any case, these reports do not substitute for clinical tests, genetic counseling or paternity/maternity tests.
