Document Summary
Messenger rna --> messages are translated into protein. Proteins are built from amino acids (there are 20) Viruses have no ability to reproduce outside its host. Daughter cells = parent cells except when there is mutation. Evolution favors mutation that will change for the better (able to survive and reproduce) Basis of evolution the process by which species become gradually modified and adapted to their env. Genes provide the instructions for cellular form, function, and complex behaviour. Genome library of genetic information in dna. Light microscopes were used to look at cells. Electron microscopes (1930) use to see details. The invention of the light microscopes led to the discovery of cells. Robert hooke(1665) examined the cork using a simple microscope and discovered cells. 19th century - microscopes began to be widely used. 2 publications by matthias schleiden (1838) and theodor schwann (1839) gave birth to cell biology. Cell theory - cell are formed by the division of existing cells.
