Biochemists have developed a new strategy for controlling the biological functions of DNA (deoxyribonucleic acid) by means of light and therefore provide a tool to investigate processes which take ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to switch genes on and off with exquisite precision. The latest work on ...

DNA stands for Deoxyribonucleic Acid, the molecule that carries the genetic code of all living things. It’s found in every cell and determines everything from your looks to your body functions. 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 ...

In the early 1980s, David Gilmour, now an emeritus biochemistry and molecular biology professor at Pennsylvania State University, joined the laboratory of geneticist and biochemist John Lis as a ...

New research published in Nature Communications has linked a normal cellular process to an accumulation of DNA mutations in ...

Children living in war-torn countries not only suffer from poor mental health outcomes, but war may cause adverse biological changes at the DNA level, which could have lifelong health impacts, ...

The findings may have important implications for diseases linked to mitochondrial dysfunction. A newly identified form of DNA damage inside mitochondria, the small structures that supply energy to our ...
