A fleeting DNA fold called i‑DNA can switch cancer‑related genes on and off, revealing a hidden structural weak point that ...

Researchers at Karolinska Institute and SciLifeLab in Sweden report they have improved the ability of a protein to repair oxidative DNA damage and created a new protein function. Their new technique ...

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health ...

DNA can mimic protein functions by folding into elaborate, three-dimensional structures, according to a new study. DNA can mimic protein functions by folding into elaborate, three-dimensional ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a double helix. That picture is still right, but it is no longer enough.

Picture in your mind a traditional "landline" telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...

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 ...
