Knowledge of the structure of DNA enabled scientists to undertake the difficult task of deciphering the detailed molecular mechanisms of two dynamic processes that are central to life: the copying of ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

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 ...

Failures in DNA replication can lead to cancer, birth defects or other harm Video shows single pieces of double-helix DNA being copied Single-molecule view gives new insights into this process ...

A new study has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some circumstances, including cancer. A new study from scientists at the ...

DNA replication is a fundamental biological process that enables the accurate duplication of an organism’s genetic material. This intricate mechanism ensures that each new cell receives a complete set ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.
