Archaea wrap their DNA (yellow) around proteins called histones (blue), shown above in a 3-D representation. The wrapped structure bears an uncanny resemblance to the eukaryotic nucleosome ...

Scientists identified two key distinctions related to the DNA replication system and the membrane. The replication system of archaea is largely unrelated to that of bacteria, but it is homologous ...

The discovery of restriction enzymes in the early 1970s heralded a new age in molecular biology. These enzymes recognize characteristic DNA sequences and cut them. Bacteria and Archaea can also use ...

In prokaryotes, DNA is bundled together in the nucleoid region ... Prokaryotes can be split into two domains, bacteria and archaea, and are unicellular organisms that lack membrane-bound structures.

For the study, the diversity of bacteria and archaea of each individual sample was determined using DNA sequences, and the diversity found in all samples from a particular biome used to determine ...

While previous research had described bidirectional promoters in eukaryotes, as well as in a few bacteria and archaea species, the new study establishes divergent transcription—the reading of genes in ...

DNA topoisomerases are a class of enzymes that ... Until recently Topo VI was thought to occur only in archaea, a domain of ...
