The structure of prokaryotes is simple. In these cells, DNA, rather than being packaged within a nucleus enclosed within a nuclear membrane, is found more loosely gathered in the cytoplasm, in the form of a body called anucleoid. This is normally in the form of a circular chromosome. The ...
Prokaryotes: Prokaryotes are living organisms that do not have nuclei or complex membrane-bound organelles. They are all unicellular. There are two types of prokaryotes. One of these types is called bacteria while the other type is called archaea. ...
a Prokaryotes are single-cell organisms, such as bacteria, that have no real nucleus and do not contain membrane-enclosed organelles. Eukaryotes, such as algae, fungi and protozoa, have a real nucleus and membrane-enclosed organelles. Viruses are tiny, complex molecules composed of protein and nu...
Is ribosomal DNA nuclear DNA? Define exons and pre-mRNA. Why doesn't E. coli have introns? Is DNA polymerase a protein? What is gene regulation in prokaryotes? What are the hallmarks of introns in molecular biology terms? Is ribosomal RNA made during transcription?

is a relatively 'modern' type of cellular life, distinguished from the more ancient prokaryotes by their distinct nuclear membrane and chromasomes, -which are lacking in prokaryotes. 真核是多孔的生活的一个相对地‘现代’类型,区别与更加古老的prokaryotes由他们的分明核膜和chromasomes, -在prokaryotes缺乏...
Unlike eukaryotic cells, prokaryote cellslack membrane-bound organelles. ... Prokaryotes lack a defined nucleus (which is where DNA and RNA are stored in eukaryotic cells), mitochondria, ER, golgi apparatus, and so on. In addition to the lack of organelles, prokaryotic cells also lack a cytosk...
Which cells do not have a nucleus? Cells that lack a nucleus are calledprokaryotic cellsand we define these cells as cells that do not have membrane-bound organelles. So, basically what we're saying is that eukaryotes have a nucleus and prokaryotes do not. ...
