Why is DNA almost always a right-handed helix? Same with alpha helices, the building blocks of proteins. Chirality, or handedness, is everywhere in biology, but the reasons can be a mystery.

Like the other great helical structure in biology, the double helix of B-DNA, it was ultimately elucidated as much by a combination of inspired modeling coupled to sound stereo-chemical principles ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

it has been said that Francis Crick "permanently altered the logic of biology". Only four years earlier, he and the young American Jim Watson had solved the double helix structure of DNA ...

The fatty membrane surrounding every living cell is a vibrant environment where countless biological processes take place.

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure ... The central dogma of molecular biology describes the flow of genetic information ...

Deoxyribonucleic acid (DNA) is the information-carrying molecule found in all living organisms. In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like ...

(Image: National Human Genome Research Institute) The discovery of DNA and its double-helix structure was a pivotal moment in ... and regulation of genes is crucial for advancing our knowledge of ...
