Ribosomes facilitate the synthesis of proteins
Why are right whales called right whales? why are right whales endangered.

What role do ribosomes play in the cell?

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.

Why are ribosomes The most important organelle?

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.

What is the main function of RNA *?

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.

Why is Golgi body important for the cell?

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.

Why are ribosomes not important?

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.

Is the powerhouse of cell?

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.

What is the most important organelle in the cell?

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.

What are the three functions of RNA?

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.

What is RNA in the human body?

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.

How is RNA important?

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.

What is the structure and function of Golgi body?

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.

What are the four functions of the Golgi apparatus?

  • Absorption of compounds: …
  • Formation of secretory vesicles and secretion: …
  • Helps in enzyme formation: …
  • Production of hormones: …
  • Storage of protein: …
  • Formation of acrosome: …
  • Formation of intracellular crystals: …
  • Milk protein droplet formation:
How many Golgi bodies are in a cell?

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.

Can ribosomes cause diseases?

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.

What happens if ribosomes are destroyed?

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.
