How does DNA recombination work? It occurs frequently in many different cell types, and it has important implications for genomic integrity, evolution, and human disease. In the alternate pathway ...

Aberrant segregation was first clearly noted in the 1950s in genetic studies of certain fungi that allow direct examination of their four haploid products of meiosis. Normally in these fungi, a ...

Oribatid mites, minuscule soil-dwelling creatures, have been decomposing organic matter for millions of years. With over ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

Marine biologists at the University of Gothenburg have identified what may be the world’s largest known clonal organism—a ...

While sexual reproduction is the predominant strategy among animals, some species have evolved the ability to reproduce asexually ...

Bjarni V. Halldorsson and Kari Stefansson, scientists at deCODE genetics, discuss the paper: Complete recombination map of the human-genome, published in Nature today. The paper continues 25 years of ...

Recombination between 2 different chromosomes has the potential to alter the genetic information in a cell. For example, when homologs recombine, loss of heterozygosity (LOH) can result, in which ...

Researchers led by Prof. TONG Minghan from the Center for Excellence in Molecular Cell Science of the Chinese Academy of Sciences, collaborating with Prof. HUANG Ying from Xinhua Hospital, Shanghai ...

Colossal Biosciences has altered several genes in mice to make them look more mammoth-like, but the company is far from its ...

is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. The techniques involve ...
