A recent paper provides an updated perspective on the evolutionary history of chelicerates—a diverse and ecologically ...

Losing Opens Up New Possibilities for Subsequent Gains Evolution is traditionally associated with increasing complexity and ...

LCRs, also called segmental duplications, are sequences that occur twice or a few times in a haploid genome. For practical purposes, the definition is limited by degree of identity (commonly >95% ...

Evolution is traditionally associated with increasing complexity and gaining new genes, but gene loss and simplification also ...

A new study in mice documents frequent undesirable repeats of DNA insertions that are not detected using standard PCR analysis ... Adding to the list of issues that can occur with CRISPR, a team of ...

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate cardiac development, are linked to nonsyndromic bicuspid aortic valve disease ...

Using the “less, but more” model, a study by the University of Barcelona identifies how massive gene losses followed by extensive gene duplications can generate evolutionary adaptations in species.

The human genome can have some quirky features, like copy number variation. When this happens, an individual carries, or loses bits of DNA, which ... | Genetics And Genomics ...

They then deployed genome sequencing to analyse the genetic effects of these structural variations on cell survival. It showed that as long as essential genes remain intact, our genomes can tolerate ...
