What else can I help you with?
Does bactieria have a nuclues?
No, bacterium do not have a nucleus. They are unicellular organisms that have their genetic material in the cytoplasm. They are classified as "prokaryotes" which literally translates to mean "pre-nucleus".
What do bacteria have instead of a nucleus?
By saying nucleus, we mean that the DNA is contained in a membrane structure, that we call the nuclear membrane. However in prokaryotes (bacteria are examples!) the nucleus is not contained in a membrane structure. On the contrary, the DNA is rather suspended inside the cytoplasm itself in a compact form and is called a nucleoid.
What does prokaryote mean in a short definition?
Prokaryotes are single-celled organisms that lack a cell nucleus and other membrane-bound organelles in their cells. They include bacteria and archaea.
What is wukaryote and prokaryote?
I believe you mean Eukaryote. These are cells that contain a nucleus and other organelles found in a membrane. We are made up of these cells.The Prokaryotes are cells with out a nucleus and other organelles. They have the materials found in eukaryotes but these are not found inside a membrane. Bacteria and algae are examples of these.
The cells of a prokaryote lack a nucleus?
First off, an English correction. You can't contain a lack of something, as there is nothing to contain. What I think you mean to ask is Do the prokaryotes lack a nucleus?If this is the question then the answer is yes, the prokaryotes (bacteria) do not contain a nucleus.
What does prokaryot mean?
before the nucleus A microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.
What does prokarote mean?
"Prokaryote" refers to a type of cell that lacks a distinct nucleus and membrane-bound organelles. Instead, the genetic material in prokaryotic cells is typically found in a region called the nucleoid. Prokaryotes include bacteria and archaea.
What do eucayotes and procayotes mean?
Eukaryotes and prokaryotes are two fundamental types of cells that make up all living organisms. Eukaryotes have a defined nucleus and membrane-bound organelles, and include organisms like animals, plants, fungi, and protists. Prokaryotes, on the other hand, lack a nucleus and membrane-bound organelles; they are generally unicellular and include bacteria and archaea. This distinction is crucial in biology as it affects how these organisms function and reproduce.
Which cell does not have a nucleus?
All of the cells of your body had a nucleus at one time but the red blood cell looses it as it matures. This makes a bit more room in the cell for more hemoglobin. Because they don't have a nucleus anymore, they can't repair themselves and they will die in about 120 days.If you mean other types of cells, the ones called the prokaryotes do not have a nucleus, they have DNA but it is not found inside a membrane. An example of this type of cell is a bacteria cell.
What would happen if the nucleus never existed?
A cell without a nucleus is called a prokaryote. Eukaryotes have a nucleus. An example of a prokaryote is bacteria. lots of cells don't have a nucleus, like prokaryotes. The human red blood cell is an example of a eukaryotic cell without a nucleus. Human red blood cells lose there nucleus when they are fully developed. Unlike prokaryotes that do not have a nucleus to begin with.
Is there anything that performs the same job as the nucleus?
The nucleoid region in prokaryotes does the same job as the nucleus in eukaryotes, but I do not think you mean this. Nothing holds the genetic information in eukaryote except the nucleus and the mitochondria and chloroplasts. So these endosymbiotic organelles could be said to be doing the same job as the nucleus.
What does protists are eukaryotes mean?
It means that protists are organisms that have a cell or cells with a true nucleus and other membrane-bound organelles. This distinguishes them from prokaryotes, which lack a nucleus and other organelles. Eukaryotic organisms also include animals, plants, and fungi.
