Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

An investigation into cellular components in bacteria has unexpectedly uncovered a feature with relevance across many life forms, paving the way for diverse research, biotechnical and medical ...

Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...

For foreign DNA to make it into a eukaryotic cell’s genome, DNA must first enter the cell, then cross the nuclear envelope, and finally insert itself into the genome. Below are a number of proposed ...

A novel type of “jumping gene” may explain why the genomes of complex cells aren’t all equally stuffed with noncoding sequences. All animals, plants, fungi and protists — which collectively make up ...

Solution to duplicating the eukaryotic genome 3 billion bps in the human genome. About 50,000 replication origins/genome. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

Researchers at University of Tsukuba have decoded the nuclear genome of Amorphochlora amoebiformis, a unicellular marine alga ...

Viruses acquire genes from eukaryotes — organisms whose cells store their DNA in a nucleus — and use them for their own function. Conversely, eukaryotes acquire genes from viruses to bring new ...
