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 ...

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 ...

New research has identified 'hotspots' in DNA where the risk for genetic mutations from transcription errors is significantly elevated. Understanding how these errors occur is important since DNA ...
