Question

Organelle which is found in both prokaryotic cells as well as in eukaryotic cells is:
(a) Ribosome
(b) Golgi apparatus
(c) Chloroplast
(d) Nucleus

Answer 1

Hint: They are specialized cell organelles composed of RNA and protein. They are present in both prokaryotic as well as eukaryotic cells. Every living cell requires it for the production of the proteins.

Complete answer:
Ribosomes are non membrane-bound organelle. They are essential cytoplasmic organelles present in close association with the endoplasmic reticulum. Ribosomes are present in the form of tiny particles in a large number of cells and are mainly composed of RNA and protein. They are named as the 70s (found in prokaryotes) or 80s (found in eukaryotes). The letter S refers to the density and the size, referred to as Svedberg’s Unit. Both 70S and 80S ribosomes are made up of two subunits. Ribosomes are either encompassed within the endoplasmic reticulum or are freely traced within the cell’s cytoplasm.
Ribosomal RNA and Ribosomal proteins are the two important components that The important function of ribosome includes are-
1. It assembles amino acids to make proteins that are important to possess cellular functions.
2. The DNA gives mRNA through the procedure of DNA transcription.
3. The mRNA is synthesized in the nucleus and transferred to the cytoplasm for the procedure of protein synthesis.
4. The ribosomal subunits in the cytoplasm leap around mRNA polymers. The tRNA then synthesizes proteins.
5. The proteins synthesized in the cytoplasm are used in the cytoplasm themself, the proteins synthesized through bound ribosomes are transported outside the cell.
together make ribosomes. The primary function of the ribosomes includes protein synthesis altogether living cells that make sure the survival of the cell.

So, the correct answer is ‘Ribosome is an organelle which is found in both the type of cells that are eukaryotic and prokaryotic cells’.

Note:
They are located in two areas of cytoplasm. They are scattered in the cytoplasm. Prokaryotes possess 70S ribosomes while eukaryotes possess 80S ribosomes. Around 62 percent of ribosomes are composed of RNA, while the rest is proteins. The structure of free and bound ribosomes is analogous and is related to protein synthesis.
