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 ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Later, in 1960, the discovery that an RNA molecule and a DNA molecule could ... But as far as their structure is concerned, these RNAs all share the same basic single-stranded chemical structure ...

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 ...

Discover how scientists captured the action of helicases in DNA replication, revealing crucial insights into this fundamental process.

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 ...

By studying this amazing structure ... matrix (in the same way that basic proteins known as histones help compact and organize nuclear DNA). To prove this idea, researchers designed a very ...

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

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...
