front 1 What is molecular biology? | back 1 -The branch of biology that deals with the structure and function of molecules essential to life (DNA, RNA, and proteins) |
front 2 These molecules carry genetic instructions, which allow cells to communicate and perform the-------- | back 2 chemical reactions needed to keep organisms alive |
front 3 The use of biology to create useful technologies and products | back 3 biotechnology |
front 4 What do we use DNA for? | back 4 - produce insulin -develop vaccines -edit genes using tools like CRISPR - analyze DNA evidence in forensic investigations |
front 5 The use of techniques from molecular biology to analyze biological evidence- blood, saliva, skin cells- and extract DNA profiles | back 5 Forensic biotechnology |
front 6 In 1830s, -Matthias Schleiden & Theodor Schwann - All organisms are made of cells -cells are the basic unit of life | back 6 The birth of cell theory |
front 7 -Charles Darwin wrote "on the origin of species" - Proposed the theory of evolution by natural selection - recognized that variation and inheritance were key to evolution, but did not know the mechanism of heredity | back 7 Transmission of genetics in 1859 |
front 8 -Gregor Mendel deciphered genetic laws - by conducting experiments on pea plants, discovered the basic -Dominant and recessive traits | back 8 transmission of genetics in 1865 |
front 9 -Friedrich Miescher isolates nuclein from white blood cells. - Walter Sutton and Theodor Boveri proposed that hereditary factors are located on chromosomes, which segregate during cell division | back 9 - 1869 -1902 |
front 10 -In 1910: - In 1911: | back 10 - Thomas Hunt Morgan discovered sex-linked genes, establishing the chromosomal theory of inheritance - A student of Morgan, discovered that the relative locations of genes can be mapped on chromosomes |
front 11 P.Levene and W. Jacobs, and others demonstrate that RNA is composed of a sugar (ribose) plus four nitrogen-containing bases, and that DNA contains a different sugar (deoxyribose) plus four bases. | back 11 In 1930s |
