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 ...
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 ...
Researchers at Duke University used CRISPR technologies to discover previously unannotated stretches of DNA in the "dark ...
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 ...
A piece that aired on NPR this week about the discovery of DNA's structure neglected to mention the significant contribution of Rosalind Franklin to that scientific milestone. And now some important ...
Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in ...
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 ...
The portal protein gp20 of bacteriophage T4 is a dodecamer located at the special five-fold vertex of the viral capsid. Its functions are essential for head assembly, genome packaging, neck and tail ...
The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...
