When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

DNA sequencing is a laboratory method used to determine the sequence of a DNA molecule. The method was developed by Frederick Sanger in 1975, who was later awarded the Nobel Prize in chemistry in 1980 ...

Here we show that DNA polymerases derived from the bacterium E. coli are considerably more prone to errors under microgravity, such as occurs in space. Our results thus have important implications for ...

Medically reviewed by Marla Anderson, MD Key Takeaways Free radicals are unstable molecules that can damage DNA, leading to ...

Scientists are working to develop an operational definition of "epigenetics" -- a rapidly growing research field that investigates heritable alterations in gene expression caused by mechanisms other ...

A storage architecture that uses synthetic DNA. Developed by molecular biologists, digital data is encoded as a sequence in the DNA and decoded by sequencing the DNA. Compared to hard drives and solid ...

A new theory that explains why the language of our genes is more complex than it needs to be also suggests that the primordial soup where life began on earth was hot and not cold, as many scientists ...
