Comparative genomic hybridization (CGH) was developed to identify pathogenic DNA copy-number changes (e.g., duplications, deletions) on a genome-wide scale, and to map these changes to genomic ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...

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 ...

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 ...

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.

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 ...

THUWAL, Saudi Arabia — Scientists have finally captured footage of the microscopic machinery that allows our cells to copy ...

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...
