Q:

What does the nucleolus do in a cell?

A:

The nucleolus of a cell is part of the production of ribosomes and contains the cell's RNA, one of the vital building blocks that tells the cell what it is. Ribosomes generate proteins that are needed for the basic functions of living cells. Cells have a roughly spherical shape, which coincides with the rounded shape of the nucleolus.

Thanks to the presence of a nucleolus, cells can generate and interact with proteins that help them generate more cells and perform other complex tasks. Proteins are large biological molecules and are part of the process of replicating DNA, making them vital in creating the building blocks of life.

Nucleoli are found only in eukaryotic cells and are a vital part of the entire structure. The structure of this cell component was first theorized properly in 1964 when studies of a species of frog yielded insightful results. Experts discovered that cells that lacked a nucleolus in their structure were not capable of life in the case of these frog eggs. Only the cells that contained a nucleolus seemed to be able to produce the necessary components to ultimately grow into a healthy new frog. The scientists who discovered this were John Gurdon and Donald Brown.

  • Q:

    Why is RNA important to the cell?

    A:

    RNA is important to cells because it relays information encoded in DNA to tiny organs within the cell, called ribosomes, which produce protein according to the RNA's instructions. RNA is thus vital to the basic functioning of the cell.

  • Q:

    At which electrode does oxidation occur in a voltaic cell?

    A:

    In a voltaic cell, the oxidation reaction occurs in the anode; this means the metal loses its electrons in this part while the other metal undergoes the reduction reaction and gains the anode's lost electrons. This redox reaction involves the transfer of electrons from one electrode to another.

  • Q:

    What is a good analogy for the functioning of the nucleolus?

    A:

    The best analogy for the nucleolus in eukaryotic cells is a factory that makes tools that are used to build other resources. The primary function of the nucleolus is to combine and construct ribosomes. The primary function of ribosomes is to build proteins necessary for the cell.

  • Q:

    What is a nucleolus?

    A:

    A nucleolus is a substructure composed of nucleic acids and proteins that is found within the nucleus of a cell. Known as the ribosome production factory, malfunction of the nucleolus has been found to cause disease in humans.
