Sequencing puts carnivore chromosomes in context

Studies comparing animal genomes generally focus on the DNA sequence itself. A new study by researchers at the University of California, Davis shows how the three-dimensional scaffolding of chromosomes is related across several ...

Sex chromosomes of birds as reservoir for jumping genes

Occurring in the genomes of most living organisms, transposable elements (TEs) are short DNA sequences that have the ability change their position. By means of various molecular mechanisms—so-called copy-paste or cut-and-paste—they ...

A missing 'motor' causes human eggs to fail

Human eggs often contain the wrong number of chromosomes, leading to miscarriages and infertility. A research team led by Melina Schuh at the Max Planck Institute (MPI) for Multidisciplinary Sciences has discovered that human ...

Genomic effects of inbreeding on Scandinavian wolves

For many years, researchers at Uppsala University have been exploring the genetic origins of the Scandinavian gray wolf population, which was founded by only three immigrating wolves. In their new study the scientists show ...

Unravelling the ancient stories hidden in DNA

Scientists have discovered that the genomes of marine invertebrates have been surprisingly stable across deep time. Published in Science Advances, this new study provides an overarching analysis of distantly related animal ...
