  1. TRANSGENIC ANIMALS Blanca Sevillano Albet Naima Balige Morales
  2. EXPLANATION OF THE TOPIC What are genetically modified (GM) animals? -A genetically modified animal is one whose genetic material has been altered by inserting, modifying, or removing certain DNA sequences in a way that does not happen naturally. -Is a process carried out in order to introduce a new trait or change a characteristic such as disease resistance in an animal. DNA is the genetic material of an organism and carries with it the instructions for all the characteristics that an organism inherits. The changes made to an animal's genetic makeup can be passed on to the next generation.
  3. HISTORY In 1982 the first transgenic animal was created, a giant mouse in which human growth hormone was incorporated into its genome. Currently, there are transgenic rats, chickens, rabbits, pigs, cows, sheep, goats, quail and fish, although the ones that we find in greater numbers are rats and mice, which represent 95% of the total.
  4. UTILITY In an astonishing advance that can make transplantation of organs from animals to humans possible, researchers have created genetically modified pigs without the presence of viruses that could cause disease in humans.
  5. EXAMPLE -Dolly the sheep was the first mammal to be cloned from an adult cell. She was a result of a nuclear combination from a donor cell differentiates an unfertilized and anucleated egg . -The cell from which Dolly came was one that was already differentiated or specialized, coming from a specific tissue, the mammary gland, of an adult animal. Dolly always lived at the Roslin Institute. There she was crossed with a male to produce six babies in total. Dolly was euthanized due to progressive lung disease.
  6. PERSONAL OPINION Our opinion is that use animals for experiments,is not good because that cause problems to them just for the good of the humans. We should let them live life in their natural places and not in laboratories suffering and dying.
