Because they constitute the smallest biological unit capable of life on its own, cells represent the building blocks for all living organisms, whether eukaryotic (plants and animals) or prokaryotic (bacteria and organisms from the domain Archaea). While eukaryotes include both single-celled and ...
1), suggest that the following classes of virus-like selfish elements emerged from the primordial gene pool and infected the first bacteria and/or archaea (Fig. 2): i) RNA-only elements, such as group I introns, ii) positive-strand RNA viruses (and, possibly, dsRNA viruses as well), ...
a, b and c. f. All of the above.In the cell structure of bacteria, do the the cells have a nucleus?Which of the following do not belong to the domain Archaea? a) prokaryotes that produce methane from carbon di...
All forms of life can generally fit into three categories: eukarya, prokarya, and archaea. The domain eukarya contains organisms that are made up of eukaryotic cells. Both domainsarchaeaandprokaryacategorize organisms that are prokaryotes. Prokaryotic cells and eukaryotic cells can be differentiated ba...
Two types of prokaryotic cells can be distinguished: bacteria and archaea. How do these cells differ from each other? Compare their cell wall structure, patterns of cytoplasmic membranes and ribosomal entities and 16S-rRNA. What organelles are the most numerous inside cells?
Archaea is one of the three domains of life. Archaea seem enriched in extremophiles and are associated with a high diversity of viral and plasmid families, many of which are specific to this domain. We explored the dataset structure by multivariate and statistical analyses, seeking to identify ...
TheftsZgene is not only widely conserved in walled bacteria but also in most wall-less bacteria and most archaea whose cell walls are different from those in bacteria23,24. TheftsZgene was acquired at a fairly early stage of evolution25,26, but the actual role of FtsZ in bacteria without ...
The major difference between viruses and plasmids is the mechanism of transferring their genomic information between host cells. Here, we describe the archaeal plasmid pR1SE from an Antarctic species of haloarchaea that transfers via a mechanism similar

vtRNA1-1 central domain mutants were generated from the Gateway cloning system entry plasmid pENTR-U243-vtRNA1-1 cloned previously [28], either with conventional PCR, QuickChange mutagenesis, or PIPE cloning. The listed primers (Supplementary Materials Table S3) were used to generate mutants M1...
