Both activators and repressors are used in both prokaryotes and eukaryotes to regulate gene expression. However, activators are more commonly used in eukaryotes, while repressors tend to be more prevalent in prokaryotes.

What do eukaryotes have but prokaryotes don't?

Eukaryotes have a nucleus and membrane-bound organelles, such as mitochondria and endoplasmic reticulum, which prokaryotes lack. Eukaryotes also have linear chromosomes, while prokaryotes have circular chromosomes. Additionally, eukaryotes often have multicellular organization, which is less common in prokaryotes.


Why the replicon in prokaryotes are larger than that of the eukaryotes?

Replicons in prokaryotes are larger than in eukaryotes because prokaryotes have a smaller and simpler genome structure compared to eukaryotes, which often have more complex genomes with non-coding regions. Prokaryotes also typically have a single circular chromosome, while eukaryotes have multiple linear chromosomes, leading to differences in replicon size. Additionally, prokaryotes often exhibit rapid growth and replication rates, necessitating larger replicons.


What are differences between Prokaryotes and Eukaryotes in what Eukaryotes have versus what Prokaryotes do not have?

Eukaryotes have membrane-bound organelles, including a nucleus that houses their DNA, while prokaryotes lack these structures and have their DNA located in a nucleoid region. Eukaryotic cells are generally larger and more complex, often forming multicellular organisms, whereas prokaryotes are typically unicellular. Additionally, eukaryotes possess cytoskeletal elements that provide structural support, which are absent in prokaryotic cells.


What is the difference between eukaryotes and prokaryotes?

Prokaryotes do not have a nucleusA eukaryote has a 'true' (membrane enclosed) nucleus and extensive system of membrane enclosed organelles, such as; mitochondria, endoplasmic reticulum, Golgi apparatus ect. and the ribosomes are found both free in the cytoplasm and attached to the rough ER. Prokaryotes have no membrane enclosed organelles or nucleus and the chromatin material is free is the cytoplasm, often in a "nuclear area", the Ribosomes in prokaryotes are all free in the cytoplasm.

What is the difference between a eukaryote or a prokaryote?

Prokaryotes do not have a nucleus, and their DNA is free floating, while eukaryotes do have a nucleus (where DNA is found).Prokaryotes usually only have a plasma membrane, DNA, ribosomes, cytoplasm, and often times a cell wall.Prokaryotic ribosomes are smaller than eukaryotic ones (by about 10S)Flagella, while shown in prokaryotes, are NOT made of microtubules.However, the most distinctive difference between the two is that the eukaryotes have a nucleus, while prokaryotes do not.Prokaryotic Cells do not have nuclear membrane While eukaryotic cells have nuclear membraneBy Mudasir Hussain SoomroStudent Of Asim Higher Secondary SchoolTando Muhammad Khan,Pakistan


What do other organisms have that prokaryotes don't?

Prokaryotes differ with other organisms in they don't have definite nucleus, nuclear envelop is absent. nucleolus is absent. no mitosis instead they show amitosis mediated by divisomes ( septasome ) which include the protein FtsZ ( filaments that are temperature sensitive Z ).


How are archae distinguished from other prokaryotes?

Archaea are distinguished from other prokaryotes by their unique cell membrane composition, which often includes ether linkages in their phospholipid bilayer instead of ester linkages like in bacteria. Additionally, archaea have distinct metabolic pathways, biochemistry, and genetic machinery that set them apart from bacteria and eukaryotes.


What are three differences between transcription in prokaryotes and transcription in eukaryotes?

In prokaryotes, transcription occurs in the cytoplasm since they lack a nucleus, while in eukaryotes, transcription occurs in the nucleus. Prokaryotic transcription is often coupled with translation, meaning ribosomes can start translating mRNA even before transcription is complete, whereas in eukaryotes, transcription and translation are spatially and temporally separated. Prokaryotic mRNA does not typically undergo extensive processing (such as splicing or capping) after transcription, whereas eukaryotic mRNA is extensively processed before being translated.


What is true of prokaryotes but not eukaryotes?

A eukaryote has a 'true' (membrane enclosed) nucleus and extensive system of membrane enclosed organelles, such as; mitochondria, endoplasmic reticulum, Golgi apparatus ect. and the ribosomes are found both free in the cytoplasm and attached to the rough ER. Prokaryotes have no membrane enclosed organelles or nucleus and the chromatin material is free is the cytoplasm, often in a "nuclear area", the Ribosomes in prokaryotes are all free in the cytoplasm.


Different between prokaryote and eukaryote?

The difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus while prokaryotes don't.Eukaryotes are multicellular and have two types- plant and animal cells. Prokaryotes are unicellular and don't have two types.Hope this helps! :)


Which of the following character is seen only in prokaryote and not in eukaryote?

One key characteristic seen only in prokaryotes is the presence of a nucleoid region, where the genetic material (DNA) is located without a surrounding membrane. Additionally, prokaryotes often have circular DNA, while eukaryotes typically have linear DNA associated with histones. Other features unique to prokaryotes include the absence of membrane-bound organelles and the presence of peptidoglycan in their cell walls (in bacteria).


Does a cell have a nucleus and cytoplasm?

well, firstly there are two main types of cells, the Prokryotes and the Eukaryotes. Prokaryotes are simple cells, often single celled organisms are Prokaryotes. Eukarotes are more complex cells and have membrane bound organells (such as Mitochondrium and ribosomes). so to answer your question, all calls have a cytoplasm, however, only Eukaryote cells have a nuclues.
