"The genetic code is this amazing thing in which a string of DNA or RNA containing sequences of four nucleotides is translated into protein sequences using 20 different amino acids," said Joanna Masel ...

DNA is the chemical that codes for proteins which determine our physical traits. This molecule is a double coil connected by cross pieces (called bases). There are four bases that can vary in sequence ...

Researchers have developed a light-induced DNA detection method that enables rapid, PCR-free genetic analysis. Their technique offers ultra-sensitive mutation detection in just five minutes, reducing ...

Professor Asaf Hellman and his research team at the Hebrew University-Hadassah Medical School have unveiled new findings in the realm of methylation-directed regulatory networks. Their study sheds ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there's a whole lot of DNA beyond genes that we are just starting to understand.

“Random DNA” is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the ...

(CNN) — Today, the view from the Takarkori rock shelter in southwestern Libya is of endless sandy dunes and barren rock, but 7,000 years ago, this region of the Sahara Desert was a far lusher, ...

A core of ice age sediment from northern Greenland has yielded the world’s oldest sequences of DNA. The 2 million-year-old DNA samples revealed the now largely lifeless polar region was once home to ...

A major new study in the journal Nature reveals a 'traffic light' mechanism controlling genetic activity within cells – a system which could potentially be targeted by cancer drugs already in ...

Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific ...
