Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus, the ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures ... you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole.

Every cell in your body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines.

Watson and Crick's discovery of DNA structure in 1953 revealed a possible ... few clues about what might be occurring at the molecular level during DNA replication. Fortunately, the models yielded ...

Earlier that morning, in the nearby Cavendish laboratory, the two scientists had discovered the structure of deoxyribonucleic acid, or DNA. This discovery changed the world of science and medicine ...
