Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958? Semiconservative ...

Not all DNA damage is equal. Every time a cell divides, it has to copy its DNA, and some stretches of the genome are harder to copy than others. Cancer cells depend on a protective response to get ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

Scientists have uncovered a surprising secret about our DNA: it’s not a static blueprint, but a constantly shifting, folding structure that helps control how genes turn on and off. Researchers at the ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

An evolutionary trait of humans and most animals is that they inherit mitochondrial DNA exclusively from the mother, even though the father's spermatozoa have mitochondria. If spermatozoa have ...

Researchers from the University of Birmingham have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. The publication of two papers ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study ...
