Are animalcules prokaryotes? Why don't prokaryotes have introns? Do bacteria have introns? Do Archaea have introns? Does bacterial DNA contain introns? Does prokaryotes or archaea have a mitochondria? Why are introns only in eukaryotic DNA?
In eukaryotic cells, genetic information is found in the form of DNA. Is this true for prokaryotic cells? How are prokaryotes and eukaryotes different in terms of the RNA polymerases involved in transcription? All viruses have: A. DNA B. a protein capsid C. a membranous envelope D. RNA ...
Since they are unicellular and do not have a well-organised cell, bacteria have been grouped under prokaryotes. However, they do show both sexual and asexual means of reproduction.Is bacteria reproduce asexually?Bacteria and archaea reproduce asexually by splitting one cell into two equal halves ...
Prokaryotes are simple, small (1-10 µ in size) and primitive type of cells. Prokaryotic cells consist of no 'well defined nucleus' and the genetic material is found scattered within the cytoplasm of cell, called nucleoid. ... Since,prokaryotes do not have nucleus, they don't have nucleo...
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 ...
Besides the phenomena of lateral gene transfer in prokaryotes, the importance of which starts only being understood (Doolittle, 1999), those of interpecific hybridization among complex organisms like metazoa are now known to be very widespread and to have played a major role in evolution, even ...
There are several types of CRISPR-Cas systems among prokaryotes but only elements of CRISPR type II are employed in genome engineering. CRISPR-Cas type II utilizes small RNA molecules (crRNA and tracrRNA) to precisely direct the effector nuclease - Cas9 - to a specifi...
This results in somewhat different predictions concerning the effect of metabolic mutations on fitness in prokaryotes and eukaryotes. The fact that bacteria are largely clonal but have often a mosaic gene structure is consistent with expectations from the model. 展开全部 机器翻译 参考文献(18) 被...
Various cellular organelles function in an organized manner to bring about the operation of different biochemical processes. The eukaryotes have well-defined organelles and nuclei, whereas prokaryotes lack such structures. They have a nucleoid that is a compact area with genetic material....
Prokaryotes: Prokaryotes are a type of single-celled organism that does not have any membrane-bound organelles. Unlike eukaryotes that have a nucleus, the DNA of prokaryotes is circular but not contained within a structure. Prokaryotic reproduction is different from eukaryotes. ...
