  1. Things To Do. Pick up cloning and selective breeding sheets.

  2. Warm Up What are the building blocks of protein? Nucleotides are composed of __________________. How can deoxyribonucleic acid be described? What does RNA stand for? In which organelle are proteins made?

  3. DNA and Modern Genetics Modern Genetics Uses DNA Technology. McDougall Littell

  4. Modern Genetics Uses DNA Technology. Organisms can be changed by manipulating their DNA. While organisms change over time with random mutations in DNA, some changes are not random. They are the result of careful breeding.

  5. Modern Genetics Uses DNA Technology. Selective breeding or Artificial breeding is the process of selecting and breeding parent organisms to pass on particular traits to the offspring. For example, all dogs share a common ancestor. But through selective breeding, there are now many types of dogs with different characteristics. Bloodhounds have been bred for a strong sense of smell.

  6. Modern Genetics Uses DNA Technology. Genetic engineering is the process in which a sequence of DNA from an organism is changed, then put back or moved to another organism. The DNA that is engineered often codes for a desired trait. One example is a genetically modified, or transgenic, plant that has a higher resistance to insects.

  7. Genetic Engineering Has Both Risks and Benefits. Some benefits of genetic engineering could include less use of pesticides and greater amounts of crops. A risk might be that a transgenic plant could start to breed with a native plant. This could give the native plant an unwanted trait, or could destroy the unique genetics of a native plant.

  8. DNA Technology Has Many Other Applications. DNA identification helps police establish if a criminal is guilty. Specialists can compare DNA evidence from a crime scene with DNA from a suspect to determine if the person was at the scene. The Human Genome Project was set up to sequence the 3 billion nucleotide pairs in a set of human chromosomes. The first sequence was published in 2001, and work still goes on to identify the 30,000 genes in the human genome.

  9. DNA Technology Has Many Other Applications. Cloning is a technique that uses technology to make copies of DNA. Cloning has been used in bacteria to make proteins and drugs to fight disease. However, there was much concern when scientists cloned a mammal, a sheep named Dolly. Since then, many people have discussed how to use cloning in the future.

  10. DNA Technology Has Many Other Applications. Other applications include making plants that produce more vitamins, and screening for genetic disorders. http://www.dnai.org/d/index.html
