Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

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 molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The backbone of the DNA double helix consists of alternating phosphate ...

Thirteen Nobel Prize winners gathered at UNESCO headquarters in Paris for a symposium to mark the fortieth anniversary of the discovery of the structure of DNA. Francis Crick and James Watson, who in ...
