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). The Nobel Prize The 1962 Nobel Prize in Physiology or Medicine was awarded for the discovery of the molecular structure of DNA – the double helix.

You can usually get more DNA to precipitate from the solution by using one of the DNA-collecting tools (such as a glass or paper clip hook) to gently lift the water solution up into the alcohol. 7. If you want to keep the DNA, store it in 50 - 70% alcohol in a sealed tube or air-dry it on paper towels or filter paper. Rosalind Franklin: Great Minds. DNA . Human Genome Project. 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. DNA - RNA - Protein. EteRNA - Played by Humans. Scored by Nature. DNA Damage.

Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells.
The odd structures are called G-quadruplexes because they form in regions of deoxyribonucleic acid (DNA) that are full of guanine, one of the DNA molecule's four building blocks, with the others being adenine, cytosine, thymine. The structure comprises four guanines held together by a type of hydrogen bonding to form a sort of squarelike shape. (The DNA molecule is itself a double strand held together by these building blocks and wrapped together like a helix.) DNA Interactive: Discovering the DNA Structure and beyond.
