Error-prone DNA replication and repair may lead to mutations and cancer in individuals who inherit a mutant copy of the BRCA1 gene, according to a new study by Weill Cornell Medicine investigators.

A new study has revealed that certain locations of DNA are copied faster than others, which could also have an effect on mutation rate. Cell division is fundamental for life, allowing organisms to ...

Using SNP-CGH to Profile for Amplifications, Duplications, and Deletions The beginnings of personalized medicine have been forged by recent advances in SNP genotyping technologies. It is now possible ...

(Inside Science) — An enzyme in the bacterium E. coli made more errors copying synthetic DNA when exposed to zero gravity than the same enzyme did in normal gravity, a recent study finds. The paper ...

Research from the Stowers Institute provides evidence suggesting that cancer cells might streamline their genomes in order to proliferate more easily. The study, conducted in both human and mouse ...

The language of life is about to expand its vocabulary. An international team of researchers discovered that the body's copying machine for DNA works in the same way for manmade, artificial building ...

Scientists look at the base pairs that compose the "rungs" of the DNA ladder to determine a genome's sequence. The success of E. coli bacteria depends on their ability to multiply very rapidly by ...

Researchers at Academia Sinica, Taiwan’s national academic institution, have identified a new form of cell division that does not involve the replication of DNA. The discovery, published in the ...
