Mitochondria are often described as the cell’s power plants, but a wave of new research suggests their genetic material may ...

Mitochondrial DNA has long been treated as a workhorse record of cellular history, but new research suggests it also hides a subtle and previously overlooked form of damage. By uncovering this cryptic ...

The Summit supercomputer revealed how damaged strands of DNA are surgically repaired by a molecular pathway called nucleotide excision repair, or NER. NER’s protein components can change shape to ...

Ultraviolet (UV) light induces principally cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts [(6-4)PPs] in DNA. Both are excised from bacterial genomes by UvrABC excision nuclease. Due to ...

Atherosclerotic plaques demonstrate extensive accumulation of oxidative DNA damage, predominantly as 8-oxoguanine (8oxoG) lesions. 8oxoG is repaired by base excision repair enzymes; however, the ...

ABSTRACT: The integrity of the chromosomes for two WIL2-derived lymphoblastoid cell lines (TK6 and WTK1) in the presence and absence of ionizing radiation was analyzed by Multiplex Ligation-Dependent ...

(Nanowerk News) A new study adds to an emerging, radically new picture of how bacterial cells continually repair faulty sections of their DNA. Such mistakes are frequent in code-copying process in ...

A new study adds to an emerging, radically new picture of how bacterial cells continually repair faulty sections of their DNA. Published online May 16 in the journal Cell, the report describes the ...
