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
The DNA has coded information for the production of specific proteins(enzymes are mostly proteins). It transfers this informtion to an RNA. The RNA with the help of ribosome strings together amino acids which together in a particular sequence form a particular protein. This protein acts as an enzyme.
