Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction in ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

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 ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once.

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 ...

Scientists have found that non-coding 'junk' DNA, far from being harmless and inert, could potentially contribute to the development of cancer. Scientists have found that non-coding 'junk' DNA, far ...

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 ...
