This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

A region of DNA that codes for a protein, often referred to as a gene, is the fundamental unit of heredity responsible for specific traits and functions within an organism. This intricate segment of ...

Researchers have achieved the most detailed view yet of how DNA folds and functions inside living cells, revealing the physical structures that ...

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in ...

James Watson, a renowned molecular biologist and one of the Nobel Prize winners for discovering the structure of DNA, died Thursday after a brief illness, according to a statement from his former ...
