Because Gamma rays can kill living cells, they are used to kill cancer cells without having to resort to difficult surgery. This is called  Radiotherapy , and works because healthy cells can repair themselves fairly well when damaged by gamma rays-but cancer cells can't. Getting the dose right is very important!
Ribosomes. Ribosomes are found in both plant and animal cells and are made in the nucleolus and transported out of the nucleus through endoplasmic reticulum. Ribosomes are important for the process of synthesis, specifically of proteins.ough Endoplasmic Reticulum: The RER is called rough because of the ribosomes attached to it. The Rough ER is necessary to create and transport proteins throughout the cell. When the ribosomes attached to the Rough ER create proteins, the proteins are sent to the Rough ER to be chemically modified for specific uses.
How do cells make proteins? Proteins are large, complex molecules, which all your cells are making continuously. Each protein is made up of many amino acids which must join together in the correct order for the protein to work properly. Imagine a car assembly line: to end up with a working car, the workers must know when and where to add each part. Likewise, the cell needs a set of commands for making proteins. This instruction manual is in your genes - found in the cell nucleus. Enlarge Building a protein is a bit like building a car: to end up with a working car, the workers on the assembly line must know when and where to add each part.
