gamma ray. A stream of electromagnetic radiation having wavelengths shorter than those of x-rays and therefore greater energy and penetrating power.. A photon of electromagnetic radiation of very short wavelength, less than about 0.01 nanometer, and very high energy, greater than about 100,000 electron volts. Gamma rays are emitted in the decay of certain radioactive nuclei and in electron-positron annihilation. 2. A narrow beam of such photons.
The ribosomes makes proteins using coded instructions that come from the nucleus
Report Abuse. A ribosome is an organelle in cells that assembles proteins. Ribosomes are composed of ribosomal RNA and ribosomal proteins (known as a Ribonucleoprotein or RNP). It translates messenger RNA (mRNA) into a polypeptide chain (e.g., a protein).It can be thought of as a factory that builds a protein from a set of genetic instructions.ibosomes are composed of ribosomal RNA and ribosomal proteins (known as a Ribonucleoprotein or RNP).
