What are ribosomes?

Question

please put this in English for me- nothing complicated. I need a simple, short definition.

Answer 1

A ribosome is a small, dense organelle in cells that assembles proteins. Ribosomes are about 20nm in diameter and are composed of 65% ribosomal RNA and 35% ribosomal proteins (known as a Ribonucleoprotein or RNP). It translates messenger RNA (mRNA) to build a polypeptide chain (e.g., a protein) using amino acids delivered by Transfer RNA (tRNA). It can be thought of as a giant enzyme that builds a protein from a set of genetic instructions. Ribosomes can float freely in the cytoplasm (the internal fluid of the cell) or bound to the endoplasmic reticulum, or to the nuclear envelope. Since ribosomes are ribozymes, it is thought that they might be remnants of the RNA world.[1] While catalysis of the peptide bond does involve the C2' hydroxyl of tRNA's P-site adenosine in a sort of proton shuttle mechanism, the full function (ie, translocation) of the ribosome is reliant on the specific change in many protein conformations.

Answer 2

Ribosomes are site for protein synthesis

Answer 3

Ribosomes are the structures where protein synthesis happens.

Answer 4

the nucleolus makes the ribosomes then they are sent out of the nuclear envelope and either attached to the ER or left floating in the cytoplasm.

Answer 5

ribosomes are tiny proteins in the cell which help arrange amino acids while the cell is making other proteins.ribosomes align the amino acids according to the DNA seuence.

Answer 6

ribosomes help in protein synthesis ...they are mainly found in the surface of rough ER.....they can also be seen in the cytoplasm.....they are produced in the nucleolus .....ans assembled in the cytoplasm....

Answer 7

A cellular structure where protein synthesis takes place....
