Sentences with phrase «archaea dna»

So Reeve and colleagues used a method called X-ray crystallography to discern, for the first time, the precise shape of archaea DNA bound to histones.

The researchers saw that archaea DNA coils around the histones, similar to the way it does in eukaryotes.

But the way archaea DNA twists around histones isn't identical to the coils of DNA seen in eukaryotes.

Not exact matches

In eukaryotes such as animals and plants, DNA is stored inside the cell nucleus, while in prokaryotes such as bacteria and archaea, the DNA is in the cell's cytoplasm.

Archaea with normal histone - DNA shapes can handle that kind of midlife crisis.

Researchers tested the importance of that rodlike architecture by tampering with the histone - DNA structures of some archaea and then observing how these mutant archaea fared in different conditions.

The resemblance between archaea and eukaryote DNA wrapping means that the first organism that used this storage scheme was an ancestor of both modern eukaryotes and archaea, the researchers conclude.

It showed that the archaea's particular DNA - histone architecture was «biologically relevant, not just a novelty,» he says.

This finding provides new insight into the evolutionary origins of the DNA - packing process and the secret to archaea's hardiness, which enables some to live in acid, boiling water or other extreme environments.

WOUND UP Archaea microbes wrap their DNA (represented in yellow) around proteins called histones (purple) akin to the way plants and animals do.

Unlike bacteria, some archaea also contain histones, but researchers weren't sure whether these microbes spool DNA around the protein bobbins the way eukaryotes do.

What Claverie calls «the final click» came after comparative analysis of Mimi's DNA with that of other organisms in life's three domains: the eukaryotes, bacteria, and archaea.

After filtering the water to catch only bacteria or archaea, they extracted DNA.

(The eukarya, thought to be descended from the archaea, rely on archaean - type genes to manage their DNA and to translate its genetic information into protein products.)

«Archaea resemble bacterial cells in size and shape but their cell cycle events — such as division and DNA replication — are a hybrid between eukaryotes and bacteria.»

Other theories hold that the prokaryotes that gave rise to early eukaryotes were probably from the Domain Archaea, both because of several key characteristics and because DNA sequence comparison suggest that archaeans are more closely related to the eukaryotes than are eubacteria.
