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...
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 ...
Do prokaryotes reproduce sexually or asexually? Prokaryotic cellscan reproduce either sexually and asexually. In a bacterial cell, sexual reproduction occurs via three different methods: conjugation, transformation, and transduction. Conjugation involves the exchange of genetic material (plasmids) between ba...
What do all eukaryotes have that prokaryotes do not have? a. cell membrane b. nucleus c. DNA d. cytoskeleton e. flagella Cell Membrane: The cell membrane is a critical component of the cell as it allows for selective diffusion of compound...

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...

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: 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. ...
