What is a possible analogy that could be compared with the structure and function of a cell?
A factory or a school. There is some boss- the nucleolus , the some managers / teachers as the nucelus, and then the workers / students as the other organelles.
What part of the cell controls everything that goes on inside it?
The Nucleus contains the Nucleolus which is the brain of the cell and produces RNA and ribosomes. RNA is what controls the ribosomes which create protein which is required for the cell. The Answers the Nucleolus
Why can't DNA enter the cytoplasm of the cell?
during transformation, cells (competent) treated with divalents which creates pores in the cell membrane are required to take up the DNA, DNA is hydrophillic then why it cannot pass through the lipid bilayer of plasma membrane where polar tails are facing outwards.
What do prokaryotic organisms lack?
No nucleus envelope - no proper nucleus No chromosomes, DNA suspended in nucleoid region and simple ring of DNA Prokaryotic cells have no nucelus. Eukaryotic cells have a nucleus. Prokaryotic cells do not have nucleus, nor membrane-bound organelles.
Who discovered archaea?
Carl Woese, of the University of Illinois, discovered archaea. He realized that while these creatures - the smallest, simplest organisms on earth - were similar to bacteria, and shared bacteria's key feature (no nucelus), their genes greatly resembled those of more advanced cells. He proposed that these new organisms be classified in their own kingdom, today known as "archaea."
What charge does the nucelus have?
Positive.
How big is a nucelus?
The average plant cell nuclei range from 7.5-10 x 10^-3 mm. a nucelus is a person.lol.
Does a nucelus inside of a cell contain DNA?
Yes!
Atom with an unstable nucelus is called?
It is a radioactive element.
How do you spell nucelus?
The center of a cell, or of an atom, is spelled "nucleus".
Where is the nucelus found?
In general the nucleus is found in the centre of every cell in one's body.
How does the Bohr model describe the atom?
It describes it because it is atom model and it had a nucelus, protoins and electrons
What does an atoms nucelus contain?
The Nucleus of an Atom contains:1. Protons (positively charged)2. Neutrons (neutral or no charge)
Is a paramecium a bacteria cell?
No, it is a single celled eukaryotic protazoa that generally feeds on bacteria. eukaryotic means it has a membrane bound nucelus.
What is the name given to a cell that has no nucelus?
Biology breaks cell types into eukaryotic (those with a defined nucleus) and prokaryotic (those with no defined nucleus).
What kind of cells contain nucleus?
All cells have nuclei (plural of "nucelus"). It's their command center. A cell without a nucleus would be like a person with no brain.
Any atom containing an unstable nucelus?
Promethium (61), technetium (43), and all others above 92 on the periodic table. Almost all isotopes of all atoms are also unstable.
