Can bacteria have an RNA genome? What organelles are found in prokaryotes? Does a RNA virus infiltrate the nucleus of the cell? Do lysogenic phages contain an RNA genome? Are there introns in prokaryotic genes? Where does ribosomal RNA accumulate?
Are there introns in prokaryotic genes? Does ribosomal RNA have introns? Do prokaryotes have exons? What are introns and what are exons? a) Introns are noncoding regions of DNA and exons are coding regions of DNA. Do archea have introns?
In prokaryotes, transfer of DNA from a donor cell to a recipient cell is mediated by direct cell–cell contact. CONSPECIFICS Members of the same species. FITNESS A measure of the capacity of an organism to survive and reproduce. HOLLIDAY JUNCTIONS ...
To answer the question why eukaryotic cells release vesicles, we may learn from prokaryotes. Bacteria release outer membrane vesicles, resembling microparticles, which act as “multi-purpose carriers”. They contain signalling molecules for other bacteria, deliver toxins to host cells and exchange DNA ...
Alpha-amylases are widely found in eukaryotes and prokaryotes. Few amino acids are conserved among these organisms, but at an intra-kingdom level, conserved protein domains exist. In animals, numerous conserved stretches are considered as typical of animal α-amylases. Searching databases, we ...
Meanwhile, in similar number of aerobic lineages (59, 56, and 46), the genes encoding these three enzymes have been detected. This result implicates the occasional occurrence of guanine oxidation in anaerobic prokaryotes. Apparently, obligate anaerobic prokaryotes and anaerobic prokaryotes suffered less...
As the evolutionary story is usually told,first came the prokaryotes: the archaea and bacteria, which are often envisioned as simple bags of enzymes without an intricate structure. Which is true of Archaea? Which is true of archaea?They contain many documented human pathogens. They have unique ...
Whole-proteome phylogeny of prokaryotes by feature frequency profiles: an alignment-free method with optimal feature resolution. Proc Natl Acad Sci U S A. 2010;107:133–8. 45. Liang Q, Luo Z, Zeng J, Chen W, Foo SS, Lee SA, et al. Zika virus NS4A and NS4B proteins deregulate Akt...
genus of fresh water green algae (Umen) that move toward the light. Although there is no accepted division of the kingdom Monera, that is, prokaryotes, into protoanimal or protoplant,E. colibacteria have been analyzed according to direct perception (Pittenger and Dent1988), and as exhibiting...
These compounds are best known as plant metabolites, but recent studies have revealed that terpenes are produced throughout the tree of life, including prokaryotes [35–38], fungi [39], and social amoebae [40]. Although terpenes of bacterial origin have been known for over a century, their ...
