DNA from the Beginning - An animated primer of 75 experiments that made modern genetics.

DNA from the Beginning - An animated primer of 75 experiments that made modern genetics.
DNA from the Beginning is organized around key concepts. The science behind each concept is explained by: animation, image gallery, video interviews, problem, biographies, and links. DNAftb blog: It's the season of hibernation, something I've always wished I could do. Oh, to wrap up in a ball, sleep away the winter, and wake to a beautiful spring day – like Bambi! Although the thought has always intrigued me, it never really occurred to me what a feat hibernation actually is.

Stages of a Landscape Architecture design project - Landscape architecture design projects differ in scale and complexity, however they are separated into various stages to allow for ease of management. Due to the variation in project types the staging of landscape architecture projects requires a flexible approach to project management. The project stages often follow a similar pattern however, they may be shortened or not undertaken due to various factors including scale, complexity, client requirements, budget and so on. I hope to assist those interested in landscape architecture by providing general information about the stages of design projects. The stage names and terminology may differ from country to country and region to region but there is a common process of managing a project through stages.

Cell, Socks, and Sex Cell, Socks, and Sex Description: This is a fun, easy way to teach the process of mitosis and meiosis. This will strengthen vocabulary concepts like homologus pairs, diploid, haploid, tetrad and many others. This lesson will also clear up concepts like sexual determination, trisomy and even twining. 10 List of tools used in genetic engineering You must have heard about genetic engineering in newspapers,TV shows,the internet etc. Sci-fi movies like X-men have also aroused your imaginations as to what miracles are possible just by altering genetic material. It must have raised curiosity as to what exactly is genetic engineering and how does it concern you as an individual. Genetic engineering involves the manipulation of genetic material (DNA) to achieve the desired goal in a pre-determined way.

Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. It's even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts. Cracking the Code of Life Cracking the Code of Life PBS Airdate: April 17, 2001 ROBERT KRULWICH: When I look at this—and these are the three billion chemical letters, instructions for a human being—my eyes glaze over. ciao! newport beach: ladies of london host midsummer Any Ladies of London fans out there? This season, the friendships between the women have shifted around a bit, somehow the drama was kept mostly civil, compared to the American housewives. And, they know a thing or two about fashion. They ALL have great style, and you can’t beat those fabulous British accents. Well, over the past few weeks, we’ve watched them traveled to Scotland, where we got a glimpse of Dundas Castle, they visited Julie Montagu at Mapperton, the Downton Abbey-like home of the Earl of Sandwich, and last week Caroline Fleming hosted a Midsummer party, complete with authentic Scandinavian food, flowy dresses and flower crowns.

Dragon Delivery Lesson Snapshot 1. Engage: Students will watch a video or look at a picture and identify all of the similarities and differences of dragons. White House Launches The National Microbiome Initiative Much of that biology is relevant to us. Soil microbes affect the viability of our farmlands. Plant microbes affect the yield of our crops. Oceanic microbes affect the circulating of oxygen, carbon, and other nutrients around the entire planet. The microbes of our buildings influence our exposure to disease-causing species. Mario's Transgenic Technology Knocks Out The Nobel Prize What's The Motivation? As a child, Capecchi wandered homeless in Italy. As a researcher, his first attempts at gene targeting were deemed not ready for funding by the National Institutes of Health. Capecchi is an individual whose personal life proves that while some events are not probable, anything is possible. Read Mario's story. During the 1980s, Capecchi devised a way to change or remove any single gene in the mouse genome, creating strains of mice that pass the altered gene from parent to offspring.

Emotion reversed in left-handers brains The way we use our hands may determine how emotions are organized in our brains, according to a recent study published in PLoS ONE by psychologists Geoffrey Brookshire and Daniel Casasanto of The New School for Social Research in New York. Motivation, the drive to approach or withdraw from physical and social stimuli, is a basic building block of human emotion. For decades, scientists have believed that approach motivation is computed mainly in the left hemisphere of the brain, and withdraw motivation in the right hemisphere. Brookshire and Casasanto's study challenges this idea, showing that a well-established pattern of brain activity, found across dozens of studies in right-handers, completely reverses in left-handers.

Getting to the Next Generation of Greenhouse Automation As with any business, you should always be looking for the next “big” thing. Apple and Samsung are always working on the next great smartphone, and, in turn, customers continue to desire and purchase that new version. So what is the next big thing to drive the greenhouse business? At Metrolina Greenhouses, we are always looking for the next great automated technology that will make our work processes more efficient and take less man hours than they do today. We have spent the past 18 months looking for machines that will transplant cuttings. Epigenetics II: DNA Methylation in Arabidopsis Jermel Watking, Bruce Nash, and David Micklos DNA Learning Center, Cold Spring Harbor Laboratory Although DNA is the blueprint of life, not all genes are actively expressed in every cell within a multicellular organism. As discussed in our Carolina Tips® article, "Epigenetics I: Using Carolina Corn Ears to Teach Genetic Imprinting," phenotypic differences between cells occur because genes are turned on or off in a cell-specific way. Many changes in gene expression are mediated by chemical modifications, such as the addition to DNA of methyl groups (CH3), which block the binding of transcription factors to promoter sequences. These changes are "above" or "over" (epi) a gene. Because they do not affect the nucleotide sequence itself, they are called "epigenetic" modifications.
