When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

Unlike nuclear DNA, mitochondrial DNA (mtDNA) is circular in nature and organized as mitochondrial nucleoids comprised of DNA-protein complexes that are distributed in the matrix. It is also inherited ...

Striking clocks, such as cuckoo clocks and automaton clocks, are not the only mechanical machines that set animated figures into motion at regular intervals. Chromatin, consisting of DNA and its ...

Scientists have found that non-coding 'junk' DNA, far from being harmless and inert, could potentially contribute to the development of cancer. Their study has shown how non-coding DNA can get in the ...

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell’s own machinery to achieve its goals. In a new work appearing online Wednesday in ...

Student teams investigate a fictional anthrax case by modeling DNA sequencing and tracking down the "guilty" lab. B. The science behind identifying the suspected lab In the anthrax case, the ...

DNA enzymatic synthesis represents an enormously valuable next step in harnessing the power of DNA replication and our ability to use it for developing cutting-edge, biotechnology solutions. DNA (or ...

Researchers discovered that stiff DNA segments inside nucleosomes physically block chromatin remodeling. The remodeling ...

Like their viral cousins, retrotransposons have been found borrowing the cell's own machinery to achieve their goals. They hijack a little-known piece of the cell's DNA repair function to close ...
