However, in the half-century since the structure of DNA was first elaborated, scientists have learned that RNA does much more than simply play a role in protein synthesis. For example, many types ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and ... This way DNA can reproduce itself without changing its structure -- except for ...

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 ...

The knot-like i-motif structure protruding from DNA’s double helix has been mapped in 50,000 locations in the human genome, concentrated in key functional areas including regions that control ...

Kinetoplastid DNA is organized into an incredible network of interlocked rings. By studying this amazing structure, how did scientists learn about RNA editing? The first tools developed for the ...

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 ... Mutations ...

Researchers have now uncovered the 3D structure of the ... can chemically modify other RNA molecules at a specific site and thus influence their function -- for example, activate them or render ...
