What is a ribosome and what does it do?
Ribosomes (/ˈraɪbəˌsoʊm, -boʊ-/) comprise a complex macromolecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.
What are the major components of a ribosome?
Ribosomes consist of two major components: the small ribosomal subunits, which read the mRNA, and the large subunits, which join amino acids to form a polypeptide chain. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins (r-protein or rProtein).
What are some real life examples of ribosomes?
The function of ribosomes is protein synthesis. They are either found freely in the cytoplasm of the cell or they are found attached to endoplasmic reticulum. Real life example: A “real life example” would be, a car factory.
What does the name ribosome mean?
The definition of a ribosome is a tiny particle made up of nucleic acids and proteins that exist in large numbers in the gel-like substance in between every cell in the body.
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. The ribosome is responsible for translating encoded messages from messenger RNA molecules to synthesize proteins from amino acids.
Why ribosomes are the most important?
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. Without free ribosomes, the various components of the cell could not function.
Why are ribosomes the best organelle?
Ribosomes are the best candidate for The Supreme Cell Organelle. Cells need protein to survive; without protein, the cell would die. Ribosomes are responsible for making the protein that regulates body processes, builds and repairs body tissue, and produces hormones.
