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.Know More
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.Learn More
The dense area within a cell that contains nucleic acids is known as the nucleolus. The nucleolus is responsible for assembling ribosomes, which are essential to protein production and organization in a cell.Full Answer >
Before a cell can begin mitosis it must grow and create proteins, RNA and copies of DNA. These activities occur in a stage of the cell cycle called interphase.Full Answer >
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.Full Answer >
The nucleolus is chiefly responsible for creating ribosomes, which in turn function as factories for protein synthesis. The nucleolus contains three main organizing regions where transcription and processing of rRNA occurs. It also purportedly aids in other processes, like the packaging of signal recognition particles and the alteration of transfer RNA. The nucleolus is located in the nucleus, and thus only exists in eukaryotic cells.Full Answer >
