Some eukaryotes consist of a single cell; but most single-celled creatures are made of simpler cells which lack obvious subdivisions and in which membranes are used almost exclusively to define the ...

Researchers found “chemical fossils” in ancient rocks containing 30-carbon steranes, a stable form of sterols present in the cell membranes of complex organisms.

CRISPR-based tools can’t easily access the DNA in these organelles, but researchers are finding other ways in.

That’s according to a recent study published in the journal Proceedings of the National Academy of Sciences, which detected ...

New work shows that physical folding of the genome to control genes located far away may have been an early evolutionary ...

The newly identified chemical fossils are special types of steranes, which are the geologically stable form of sterols, such as cholesterol, that are found in the cell membranes of complex ... the ...

Scientists at the Research Institute for Farm Animal Biology (FBN) in Dummerstorf and the University of Udine have detected ...
