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 was discovered in 1869 ... The next step was to find out its structure, in order to understand how the gene, the basic unit of heredity, works and how it is passed from one generation to ...

DNA is negatively charged, due to the phosphate groups in its phosphate-sugar backbone, so histones bind with DNA very tightly. The basic repeating ... quite the uniform structure depicted in ...

Understanding this structure is essential for studying heredity and genetic information. (Image: National Human Genome Research Institute) The discovery of DNA and its double-helix structure was a ...

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 can be cut up and separated, which can form a 'bar code' that is different from one person to the next. The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a ...

MSK researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a ...
