The YouTube video discusses the concept of nuclear transfer and the advantages and disadvantages of genetic manipulation. Nuclear transfer is the process of transferring nuclear material from one organism to another, and can be used to clone a living being or improve a species. Some advantages of nuclear transfer include the ability to mass-produce substances needed for medicine, the possibility of improving crops, and the opportunity to correct genetic defects that cause diseases. Some disadvantages of nuclear transfer include ethical and moral implications, as well as the possibility of premature aging in cloned animals.

  • 00:00:00 This video discusses the concept of nuclear transfer, or the transfer of nuclear material from one organism to another. It covers the three stages of nuclear transfer: enucleation, transfer of the nucleus, and activation. The video also mentions the use of genetic engineering techniques, such as altering or deleting genes, to achieve certain goals.
  • 00:05:00 The video discusses the advantages and disadvantages of genetic manipulation. Inge Perm provides a pathway for conducting previously impossible tasks, such as cloning a living being or improving the species. Some of the advantages include the ability to obtain massive amounts of bioactive substances needed for medicine. These substances can be used to fight diseases and improve health in the human population. This technology can be applied to vaccines or other compounds. The possibility of improving significantly the food industry can help combat hunger and malnutrition in the world. Crops that are more resistant to climate change or produce larger, more nutritious fruits are also possible. The opportunity to correct genetic defects that cause diseases through targeted gene editing is also an advantage. However, as with any technology, there is also a downside. Some of the disadvantages observed include ethical and moral implications that compel people to replace the human body spot in the order of things. Dolly the cloned sheep was born at the Roslin Institute in Scotland on July 5, 1996. As mentioned earlier, the cloning of a live being is not a random event but the result of decades of research by many scientists. Dolly the famous sheep did not travel much because she lived at the Roslin Institute where she was reportedly the most compliant sheep observed and best treated of all time
  • 00:10:00 Dolly the sheep was the first mammal to be cloned from an adult cell, and the discovery has had a significant impact on the field of science. Dolly was born from cells that had been taken from an adult sheep and had the ability to regenerate cells. However, her life was cut short due to a respiratory illness at the age of 6. Before she died, scientists had predicted that she may experience premature aging. Her cloning procedure consisted of preparing cells in a state of equilibria, which is when they are between the states of dormancy and active growth. These cells were then injected into another sheep, which acted as a receptor. Dolly's cells were then kept in a culture medium with fetal bovine serum and five days of continual stimulation with gonadotropin hormone, before being transferred to a 5% CO2 and 0% calcium environment. Her eggs were then fertilized with a sperm and transferred to a receptive female. After six days, they developed into embryos, which were then transferred to another female. Once they were transferred, the embryos were kept in a 10% fetal bovine serum and 0.5% citric acid environment. After six more days, they were transferred to the recipient female's uterus. D
