WebbRibosomes help cells remain in a healthy condition by reacting with other parts of the cell. One such part is the nucleus, the cell’s nucleus and Ribosomes work together to make proteins. This complete process of making proteins is called “Translation” and uses amino acids in the body for its successful operation. WebbRibosome formation is a highly dynamic and coordinated multistep process, which requires synthesis, processing and modification of pre-rRNAs, assembly with ribosomal proteins and transient interaction of numerous non-ribosomal factors with the evolving pre-ribosomal particles.
