where are ribosomes found facts, news, stories and more
Ribosomes are small, complex structures that are found in cells throughout the body. They are responsible for synthesizing proteins, which are essential for the proper functioning of the body.Ribosomes are found in two main locations within cells: the cytoplasm and the endoplasmic reticulum (ER). In the cytoplasm, ribosomes are free-floating and are responsible for synthesizing proteins that will be used within the cell. These proteins include enzymes, structural proteins, and other molecules that are necessary for the cell to function properly.In the ER, ribosomes are bound to the surface of the organelle. These ribosomes are responsible for synthesizing proteins that will be secreted from the cell or sent to other parts of the cell, such as the mitochondria or the nucleus. These proteins include hormones, immune system proteins, and other molecules that are necessary for the cell to communicate with its surroundings.Ribosomes are composed of two subunits, the small subunit and the large subunit. The small subunit is responsible for recognizing the sequence of the messenger RNA (mRNA) that is being translated, while the large subunit is responsible for catalyzing the formation of peptide bonds between amino acids.Ribosomes are incredibly important for the proper functioning of the body. Without them, cells would not be able to produce the proteins that are necessary for survival. Additionally, ribosomes play a key role in the regulation of gene expression, as they are responsible for transcribing the genetic information stored in DNA into functional proteins.One of the most well-known diseases caused by defects in ribosomes is congenital dyserythropoietic anemia (CDA). CDA is a rare inherited disorder characterized by the abnormal development of red blood cells. It is caused by mutations in the genes that encode for the components of the ribosomes.In conclusion, ribosomes are small and complex structures that are found in cells throughout the body and are responsible for synthesizing proteins. These proteins are necessary for the proper functioning of the cell and the body as a whole. Ribosomes are found in the cytoplasm, where they produce proteins that will be used within the cell, and in the endoplasmic reticulum, where they produce proteins that will be secreted from the cell or sent to other parts of the cell. Defects in ribosomes can cause a variety of diseases, including congenital dyserythropoietic anemia.
