They used worms with a mutation in a cuticle collagen gene, which makes it easier for ... the frequency with which these X chromosomes will not partition properly goes up significantly,” explained ...

Transposons, or "jumping genes"—DNA segments that can move from one ... can target and insert themselves at the ends of linear chromosomes, called telomeres, within their bacterial host.

2 This technique, adapted for ancient samples and combined with DNA sequencing, enabled the researchers to map the chromosome features, assemble a reference genome, and determine activation patterns ...

Researchers have shed new light on how a type of heart valve disease -- aortic valve stenosis -- progresses differently in males and females.

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

Transposons, or "jumping genes"—DNA segments that can move from one ... For one, inserting at the end of the chromosome helps the transposon avoid genes for the cell's core functioning, which ...
