A ribosome is a complex macromolecular structure in the cell which is involved in the process of translation. This is an essential function of all living cells, allowing for the production of proteins and all manner of biological structures.
Ribosomes are important because they are responsible for protein synthesis. Free ribosomes, in particular, are important because they produce proteins essential for internal cellular activity, which are not synthesized elsewhere.
The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.
Ribosomes are organelles that create proteins. Cells use proteins to perform important functions such as repairing cellular damage and directing chemical processes. … Without these ribosomes, cells would not be able to produce protein and would not be able to function properly.
The mitochondria, often labeled the powerhouse of the cell, are the organelle responsible for energy production within the cell. Playing an important role in cellular respiration, the mitochondria are the main location for ATP production.
The nucleus is the most important organelle in the cell. It contains the genetic material, the DNA, which is responsible for controlling and directing all the activities of the cell. All the RNAs needed for the cell are synthesised in the nucleus.
There are three types of RNA involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribisomal RNA (rRNA). All three of these nucleic acids work together to produce a protein. The mRNA takes the genetic instructions from the nucleus to the cytoplasm, where the ribosomes are located.
RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses.
RNA–in this role–is the “DNA photocopy” of the cell. … In a number of clinically important viruses RNA, rather than DNA, carries the viral genetic information. RNA also plays an important role in regulating cellular processes–from cell division, differentiation and growth to cell aging and death.
The Golgi apparatus is a central intracellular membrane-bound organelle with key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids. To best perform these functions, Golgi membranes form a unique stacked structure.

The number of compartments in any one Golgi apparatus is usually between 3 and 8. The number of sets of Golgi apparatus in a cell can be as few as 1, as in many animal cells, or many hundreds as in some plant cells. Specialised secretory cells contain more sets of Golgi apparatus than do other cells.
Ribosomes are essential for life, generating all of the proteins required for cells to grow. Mutations in some of the proteins that make ribosomes cause disorders characterized by bone marrow failure and anemia early in life, followed by elevated cancer risk in middle age.
If the ribosomes of a cell were destroyed, what effect would this most likely have on the cell? … The cell would be unable to synthesize proteins. It would stimulate mitotic cell division Increased protein absorption would occur through the cell membrane.
