In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes ...

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 95, No. 15 (Jul. 21, 1998), pp. 8550-8555 (6 pages) Prokaryotic chromosomes and plasmids encode partitioning ...

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 ...

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning “true kernel”) have a cell nucleus that harbours most of the cell’s genetic information and ...

Transposons, mobile DNA elements found in the genomes of prokaryotic and eukaryotic organisms, move randomly from one site in a chromosome to another using a process catalyzed by transposases. This ...
