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 ...

How does DNA structure itself from the very first moments of life? A team of researchers has just observed that DNA adopts a defined three-dimensional architecture much more rapidly than ...

The genome is more than a linear code; it is a dynamic structure whose three-dimensional folding dictates how genes are regulated. Traditional sequencing technologies capture base-level variation but ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

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 ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

Add Yahoo as a preferred source to see more of our stories on Google. James Watson in 1993: he called Prince Charles ‘a Luddite’ and controversially portrayed Rosalind Franklin as being dour, dowdy ...

One of the most important milestones in modern science, does April 25 also mark the date of an intellectual heist? As has been well-documented, a third person contributed to the discovery — the ...
