Cell Bio Bites Topic: Ribosomal Function and Ricin Relevance of Ricin and Ribosomes Relevance of Ricin and Ribosomes Most foods from the four food groups contain protein. Protein is manufactured by the ribosome. In contrast to ribosomes‚ ricin breaks up proteins and blocks protein synthesis. In that perspective‚ ribosomes can be seen helpful and ricin as useless and lethal to a somatic cell. Luckily‚ since ricin can stop protein synthesis‚ ricin is being experimented to block diseases’ protein

The Origin and Evolution of Life on Earth Why do we start the discussion of biology with a discussion of geology? Here are some reasons why one would do this: * All life on earth is linked to geology; likewise‚ many surface geologic features and processes have been influenced by life on earth. The origin and early evolution of the earth are especially important when looking at the origin and early evolution of life on earth. * Life chemistry had its origin with the elements available to
