A subtle failure during cell division can set off dramatically different outcomes, according to new research exploring whole ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

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 ...

Loss of an enzyme necessary for a process called lipoylation disrupts the way cancer cells copy their DNA, increasing their ...

DNA-folding nanorobots can manufacture limitless copies of themselves By Loz Blain December 08, 2023 Tiny nano-robots have been developed that can grab tiny snippets of DNA and assemble them into new ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

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 ...

Researchers have revealed the relationship between autophagy and polyploidy, the latter a phenomenon in which cells contain multiple copies of genetic material. In this regard, they have discovered a ...

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 ...

Ribosomal DNA (rDNA) is present in hundreds of copies in the genome, but has not previously been part of genetic analyses. A new study of 500,000 individuals indicates that people who have more copies ...
