New Genetic Twist: 4-Stranded DNA Lurks in Human Cells 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.

Completed in April 2003, the HGP gave us the ability, for the first time, to read nature's complete genetic blueprint for building a human being.

Chromosomes are the structures that hold genes. Genes are the individual instructions that tell our bodies how to develop and function; they govern physical and medical characteristics, such as hair color, blood type and susceptibility to disease. The Fruit Fly and Genetics Personals: ♀ FF, Se/E/Dp, seeks ♂ FF, +/+/+ for short term relationship. Enjoys romance, fermentation, and long walks on the peach... You know those annoying little bugs that like to get in your fruit if you leave it on the counter? Well they're called Drosophila melanogaster (or just fruit flies) and they've been used to study genetics for over 100 years. This interactive website is designed to introduce biology students to research on model organisms while reviewing genetics basics. Learning about Genetics Using Flies
