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 ...

Copy number variants (CNVs) arise by homologous recombination (HR) between repeated sequences (recurrent CNVs) or by non-homologous recombination mechanisms that occur throughout the genome (non ...

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 ...

Adding to the list of issues that can occur with CRISPR, a team of researchers now reports a high frequency of unwanted duplications while engineering genetic insertions in mice. Worryingly to the ...

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

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 ...
