They observe how the mobile DNA LINE-1 copies its sequence in human cells, revealing the precise mechanism of the ORF2p gene.

Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate ...

Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists from the German Cancer Research Center (DKFZ) and the Universities of Cambridge and ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

CHAMPAIGN, Ill. — Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth ...

Long interspersed nuclear element-1 (LINE-1 or L1) is the only active, self-copying genetic element in the human ...

When strands of DNA - our genetic building blocks - are damaged ... And is this an isolated case or part of a broader evolutionary pattern?" Most importantly, scientists want to know what they can ...
