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
Enzymes are folded proteins. Proteins are made by ribosomes in the cell. To be specific, information in the nucleus (DNA) is transcripted to mRNA which leaves the nucleus to g â¦ o to a ribosome to help it assemble amino acids (which are the building blocks of protein).
