The left-handed Z-DNA double helix is held together by traditional Watson-Crick base pairs ... Z-DNA exists transiently in short stretches of up to 100 base pairs within some right-handed DNA ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...

Why is the heart slightly on the left side of the body for most people? Why is DNA almost always a right-handed helix? Same ...

Lefties, unite: a groundbreaking new study has uncovered a link between human DNA and the gift ... a good chance you’re left-handed. The world may be designed towards right-handed people ...

Sanger sequencing (left) sequences 500-700 bases per reaction with 16 reactions per gel. Massively parallel DNA sequencing (center) sequences 100-5,000 bases per reaction with 10 thousand to 10 ...

Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide are attached to the nitrogenous bases within another polynucleotide ...

Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll ...
