My Firsthand Experience: How GMOs Cause Farmer Suicide. By Dr. Mercola It's been called the "largest wave of recorded suicides in human historyi. " Indian farmers have been robbed of their livelihoods, causing them to take their own lives in despair.Over the past 16 years, it is estimated that more than a quarter of a million Indian farmers have committed suicide.Who is responsible for this tragedy? The most obvious culprits are global corporations like Monsanto, Cargill and Syngenta and the genetically engineered seed they have forced upon farmers worldwide. None are hit harder than those in India, where socioeconomic and environmental factors have magnified the impact, making it almost impossible for these farmers to survive.In fact, genetically engineered seeds are so fundamental to the problem that it's been termed "GM Genocide. " I personally visited India when I met with Organic India. A Farmer Commits Suicide by Pesticide Every 30 Minutes in India The statistics are staggering.

India's "Suicide Belt" Here I am with local Indian farmers. The science checklist applied: Solving DNA's double helix.

Closer than ever… The million-to-one black and white twins Kian and Remee turn seven One is black and has big brown eyes. The other is a blue-eyed blonde with the palest of skin. They might share the same cheeky smile, but side by side, they could hardly look less alike. Yet remarkably, Kian and Remee are twins, born a minute apart. Loving: Black and white twin sisters Kian (left) and Remee (right), seven years after they came into the world The pair owe their appearance to a one in a million combination of their parents’ genes. Mother Kylee Hodgson and father Remi Horder both have white mothers and black fathers.

The startling result is a two-tone set of delightful little girls. They first attracted international attention when they were featured in the Mail at less than a year old. Now, approaching their seventh birthday, they have never asked why they don’t look the same, nor have they ever experienced any racial prejudice. Time, however, only accentuated their differences.

Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA. Abstract This lesson examines the amount of deoxyribonucleic acid, or DNA, in cells. The first part emphasizes math skills as the students determine the size of a bacterium. Then the students are asked to decide how long the chromosome of a bacterium is compared to its length using data on known genome sequences.

Next, this size differential is demonstrated using a model composed of a plastic egg and dental floss. Intended Audience Learning Objectives By completing this activity, the student will be able to: Understand more fully how the length of DNA relates to the size of the cell.2. Necessary Student BackgroundStudents should have prior knowledge of the presence of DNA within the cell.

The Biology Project. Graphics Gallery. Exhibit: Mutant Fruit Flies - Drosophila Genetics. Click on the small thumbnail pictures below to magnify the flies. You'll see enlarged illustrations of fruit flies, Drosophila melanogaster. (In our real exhibit you'd be looking at the actual flies crawling around, looking for food or grooming their wings.) Compare the mutated flies to the normal flies. The fruit flies in this exhibit show just a few of the mutations that occur in natural fruit fly populations. The genetic instructions to build a fruit fly-or any other organism-are imprinted in its DNA, a long, threadlike molecule packaged in bundles called chromosomes.

Like a phone book made up of different names and addresses, each chromosome consists of many individual sections called genes. To build a complete organism, many genes must work precisely together. Mutations are neither good nor bad: some may be beneficial for an organism; others may be lethal. Biologists learn about the proper function of any gene by studying mutations. Analyzing Spooled DNA. Life Science | Session 5. Lesson at a Glance: Curriculum: Exploring with Wisconsin Fast Plants, Kendall/Hunt Publishing Company Grade: Sixth Topic: Variation, Heredity, and Evolution< Kathleen, like Sally Florkiewicz in Program Four, worked with Fast Plants; however, where Sally used them to illustrate the plant life cycle to her third graders, Kathleen used them to demonstrate variation among plant populations to her sixth graders.

Kathleen explained that most of the setup for the lesson took place early in the year when she was showing her students how to do a controlled experiment. In that activity, she had each of her students care for six Fast Plants: two served as the controls, two had low doses of salt in their water, and the final two had high doses of salt in their water. Her students watered the plants using graduated cylinders and measured and recorded the height, number of leaves, and number of flowers on each of the plants for a period of several weeks. DNA . Genetics. DNA . Genetics. 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. In addition, some genes have more than two different versions. Now that you know a little about blood types, let's learn about the genes that code for them. DNA . Intro. Rediscovering Biology - Case Studies: Designing Cancer Drugs. Although they are best known for their use in agriculture to increase yields and fight crop diseases, genetic modification techniques are used in many different areas of biological research, including medicine. In this case study, we'll follow the process of developing an edible vaccine for the hepatitis B virus and explore practical details of genetic engineering techniques.

The current hepatitis B vaccine is a recombinant subunit produced in yeast. Subunit vaccines are viral proteins that elicit an immune response without viral genetic material. The current vaccine is effective, but cost-prohibitive for economically challenged areas. A better option that is more easily administered might be an edible vaccine from a plant genetically modified to express a hepatitis B protein. No needles are required — the vaccine is just eaten. People with blue eyes have common ancestor. 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).

DNA: The book of you - Joe Hanson. Cold Spring Harbor Laboratory (CSHL) is a private, not-for-profit research and education institution at the forefront of molecular biology and genetics. Was an annus mirabilis for science. Here are five classic papers from Nature that describe and provide evidence for the double helix being the structure of DNA, and one from The Journal of Experimental Medicine that has been described as the "defining moment in nucleic acid research. " is an incredible picture of unlinked DNA under the electron microscope.

Acid (DNA) molecules are informational molecules encoding the genetic instructions used in the development and functioning of all known living organisms and many viruses.
