Prokaryotes: Prokaryotes are those organisms that do not have a true nucleus and membrane-bound organelles. Their genetic material is instead located floating in an area known as the nucleoid. The chromosomes of prokaryotes are not held in a membrane-bound nucleus. Suggest Corrections 2 Similar que...
Do prokaryotic cells have a nucleus? Learn the answers to questions like: what do prokaryotic cells have instead of a nucleus, and do prokaryotic cells have DNA. Related to this Question Do human cells have RNA? What RNA subunits are ribosomes made of in prokaryotes and eukaryotes?
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 nucleic acid, that cann Prokaryotes是单细胞有机体,例如细菌,没...
Prokaryotes are thought to be examples of some of the earliest forms of life to exist on the planet. Their internal structures are much less organized and defined than those of eukaryotes who developed later.Answer and Explanation: Eukaryotes have both introns and exons in their DNA. This ...
You already know that animal cells consist ofa cell membrane, nucleus and a fluid cytoplasm. Do prokaryotes have cytoplasm? Most prokaryotes are small, single-celled organisms that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane, but theyhave no internal mem...
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. ...
Do all prokaryotes have flagella? All prokaryotic cells are encased by a cell wall. ... Flagella and some pili areused for locomotion, fimbriae help the cell stick to a surface, and sex pili are used for DNA exchange. Most prokaryotic cells have a single circular chromosome. They may also...
is replicated in S phase of cell cycle C:eukaryotic DNA contains multiple origins D:the replication origin of eukaryotes is shorter than that in prokaryotes 答案:ABCD 11. The Okazaki fragment of eukaryotes is longer than that of prokaryotes.( ) ...
All cells also have ribosomes. In prokaryotes, these float freely in the cytoplasm; in eukaryotes they are typically bound to the endoplasmic reticulum. Ribosomes are often classified as a type of organelle, but in some schemes they do not qualify as such because they lack a membrane. Not ...
Prokaryotes vs Eukaryotes Pro> has no nucleus & have a single, circular chromosome located in a nucleoid. ; eukaryotes do have a nucleus surrounded by a complex nuclear membrane that contains multiple, rod-shaped chromosomes.Pro> Archaea a...
