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

Bethesda, MD - Scientists have discovered a DNA sequence that is involved in controlling the timing of DNA replication. Because alterations in DNA replication timing are associated with cancer, this ...

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 ...

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 ...

For biologists everywhere, April 25 is auspicious. It is DNA Day and commemorates the date in 1953 when scientists Francis Crick, Rosalind Franklin, James Watson and Maurice Wilkins published seminal ...

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 ...
