MYCN v-myc myelocytomatosis viral related oncogene, neuroblastoma derived (avian) [Homo sapiens] - Gene result Sleep: Genes Cause People to React Differently to Lack of Sleep, Says Study <br/><a href=" US News</a> | <a href=" Business News</a> Copy No matter how little they sleep, some people can keep a skip in their step while others will yawn and struggle through the day. A new study from the University of Pennsylvania School of Medicine found that the reason could be in our genes. Researchers found that healthy people with one particular genetic variant were generally sleepier than those without the gene. About 25 percent of the general public has the genetic variant, called DQB1 *0602, but only a small percentage of them actually suffer from sleep problems. One person who has been told by his doctor that he may have this genetic variation is Robert Gibson, a 43-year-old machine shop supervisor in Milan, Illinois. "It feels like I am drugged down, like there's a heavy weight on me the whole next day," said Gibson. Genes and Heavy-Eyes

But when scientist Eric Lander looks at this he sees stories. ERIC LANDER (Whitehead Institute/MIT): The genome is a storybook that's been edited for a couple billion years. ROBERT KRULWICH: This is the story of one of the greatest scientific adventures ever, and at the heart of it is a small, very powerful molecule, DNA. For the past ten years, scientists all over the world have been painstakingly trying to read the tiny instructions buried inside our DNA. J. FRANCIS COLLINS (National Human Genome Research Institute): This is the ultimate imaginable thing that one could do scientifically...is to go and look at our own instruction book and then try to figure out what it's telling us. ROBERT KRULWICH: And what it's telling us is so surprising and so strange and so unexpected. I'm Robert Krulwich. DR.

MOUNTAIN VIEW, CA – January 11, 2011 – 23andMe has released its first annual list of what it felt to be the 10 most interesting and significant genetic findings in 2010, as part of an ongoing journey to understand the role of genetics in personal health and human development. "Our understanding of the human genome is accelerating at a phenomenal rate," stated Anne Wojcicki, co-founder and CEO of 23andMe. Customers of 23andMe have the opportunity to learn about how their genetics can influence their individual health traits, risk for developing certain diseases and conditions, reactions to a variety of medications, and ancestry. 1.

Talking Glossary of Genetic Terms Glossary Home | Text Version Designed to help learners at any level better understand genetic terms Guided by national science standards Explained by scientists at the NIH The National Human Genome Research Institute (NHGRI) created the Talking Glossary of Genetic Terms to help everyone understand the terms and concepts used in genetic research. In addition to definitions, specialists in the field of genetics share their descriptions of terms, and many terms include images, animation and links to related terms. Enter a search term or explore the list of terms by selecting a letter from the alphabet on the left and then select from the terms revealed. The Talking Glossary At the bottom of most pages in the Talking Glossary are links to help you get the most out of this glossary.

CANTANKEROUS NEIL DEGRASSE TYSON: Yep, whatever. CHEERFUL NEIL DEGRASSE TYSON: As they get older, those differences can get more pronounced. Two people start out the same but their appearance and their health can diverge. CANTANKEROUS NEIL DEGRASSE TYSON: No. CHEERFUL NEIL DEGRASSE TYSON: Yeah. CANTANKEROUS NEIL DEGRASSE TYSON: And don't our genes make us who we are? CHEERFUL NEIL DEGRASSE TYSON: Well they do, yes, but they're not the whole story. CANTANKEROUS NEIL DEGRASSE TYSON: Yeah, you're heavier, and I'm better looking. CHEERFUL NEIL DEGRASSE TYSON: Yeah, whatever. NEIL DEGRASSE TYSON: Imagine coming into the world with a person so like yourself, that for a time you don't understand mirrors. CONCEPCIÓN: As a child, when I looked in the mirror I'd say, "That's my sister." RANDY JIRTLE: Sure.
Exploring Genomics Data The Genomics Explorers provide an iterative way for students to choose strategies for asking and addressing biologically interesting questions using a range of genomics tools. Select which Explorer you wish to explore: The Genomics Explorer helps students: become inspired about biology develop a literature-based understanding of important quantitative approaches, define interesting questions that can be addressed with data, make connections between genes and their biological functions, analyze and critically evaluate bioinformatic data, connect bioinformatic analyses with wet lab and field experiments, develop and test a viable hypothesis by bringing together the literature, classroom knowledge, and analysis of data.

The Ductile Helix: "Jumping Genes" May Influence Brain Activity Mobile DNA molecules that jump from one location in the genome to another may contribute to neurological diseases and could have subtle influences on normal brain function and behavior, according to a study published October 30 in Nature. (Scientific American is part of Nature Publishing Group.) Retrotransposons are mobile genetic elements that use a copy-and-paste mechanism to insert extra copies of themselves throughout the genome. Researchers from the Roslin Institute in Edinburgh, Scotland, have now comprehensively mapped retrotransposon insertion sites in the genomes of normal human brain cells for the first time. They used state-of-the-art DNA sequencing technology to screen for retrotransposons in tissue samples taken postmortem from three individuals who were healthy when alive and had no neurological disease or signs of abnormality in their brain tissue. "Each sample had its own set of unique retrotransposition events," senior author Geoffrey Faulkner says.
The Illustrated Guide to Epigenetics Illustrations by Joe Kloc This month marks the ten-year anniversary of the sequencing of the human genome, that noble achievement underpinning the less noble sales of 23andMe's direct-to-consumer genetic tests. To commemorate the scientific occasion, we've created an illustrated introduction to one subfield of genetics likely to produce even more dubious novelty science projects someday: epigenetics. What is epigenetics? Human life begins as a single cell equipped with all of the genetic information—known as the genome—it will need to develop into a full-grown adult. FIGURE 1: Through a process called mitosis, a single cell (A) splits into two cells (B) with identical genetic information. FIGURE 2: DNA coils around proteins called histones, forming a nucleosome. How does the epigenome work? Molecular "caps" called methyl groups can be attached to genes in order to effectively block them from giving instructions to the cell (FIGURE 3). Where do the different epigenomes come from?
