Ever since the first general surveys of nuclear DNA content were carried out in the early 1950s, it has been apparent that eukaryotic genome sizes vary enormously and that this is unrelated to ...

Scanning electron micrograph of the syn6.5 strain of yeast, which has about 31% synthetic DNA. [Cell/Zhao et al.] “We decided that it was important to produce something that was very heavily ...

A decade ago, the existence of Asgard archaea was unknown. However, in 2015, researchers analyzing deep-sea sediments uncovered gene fragments that suggested the presence of a new, previously ...

Yizhi “Patrick” Cai is coordinating a global effort to write a complete synthetic yeast genome. If he succeeds, the resulting cell will be the artificial ... clean-slate approach is the guiding ...

But eukaryotes have a different genome architecture, known as asymmetrical. The key advantage of the eukaryotic genome arrangement is that they don't have to maintain genome copies all over the ...

Elizabeth Kellogg, PhD, St. Jude Department of Structural Biology, used cryo-EM to study the evolutionary journey of Fanzor2, a compact eukaryotic genome-editing protein with huge potential ...

Unlike CRISPR proteins, Fanzor enzymes are encoded in the eukaryotic genome within transposable elements and the team's phylogenetic analysis suggests that the Fanzor genes have migrated from ...

S ince the bacterial-origin CRISPR-Cas system rose to popularity as a genome editing tool, scientists have wondered whether other genome editors exist in nature. Now, two independent research teams ...

The fern’s genome is 61,000 times the size of the smallest eukaryotic genome. “A great mystery is the meaning of all of this variation—how do genomes grow and shrink, ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

Under this population pressure, prokaryotes and eukaryotes might respond differently — the former in a way that creates barriers to evolving multicellularity, and the latter in a way that accelerates ...
