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
Organ systems which produce many proteins have cells with a large amount of rough endoplasmic reticulum. The smooth endoplasmic reticulum plays a major role in synthesizing lipids by means of enzymes embedded in these smooth membranes.he ribosomes on the rough endoplasmic reticulum manufacture proteins which enter the channels of the endoplasmic reticulum and move to places where they can create pockets.
