- All transgenic species are capable of passing on their foreign genes to their progeny.Do you agree or disagree why? Prior to this video I had not been introduced to the concept of genetically modified babies or "designer babies". However, a concept that was brought up in comparison to the designer babies was IVF babies. This concept is more familiar to me and made me think of the great possibilities designer babies could bring, but at what cost? As IVF first became popular it seemed to be well known that was was a possibility for well-off financially families. Although designer babies may have benefits such as lowering the risk to develop hereditary diseases, I don't think this concept would be widely accessible to varying income levels.Do all of them True/False 31) The process by which an electrical charge is used to introduce DNA into a cell to produce a transgenic organism is called electroporation.Answer: 32) Reproductive cloning is used to produce large amounts of mammalian proteins from transgenic agricultural animals such as cattle.Answer: 33) In gene addition, homologous recombination is used to remove the original gene and replace it with the cloned gene.Answer: 34) All stem cells have the potential to differentiateAnswer: 35) A bone marrow transplant involves the transfer of multipotent stem cellsAnswer: 36) The fact that in mammalian systems multiple genes may compensate for the loss of a gene is called gene redundancy.Answer:
- Transgenic organisms are produced by: addition, deletion or modification of genes O genetic transformation by bacteria O chromosomal aberrations O hereditary genetic mutationsWhich of the following statements is TRUE about reverse genetics? OReverse genetics analysis starts with mutants with altered phenotypes and identifies the genetic causes of the mutant phenotypes. Reverse genetics can be performed by random mutagenesis but not targeted mutagenesis. Reverse genetics analysis starts with a known DNA sequence, mRNA, or protein. Reverse genetics analysis relies on controlled crosses between mutants with distinct phenotypes.When creating transgenic mice, in which generation would a researcher hope to see homozygous transgenic animals? O F4 O F3 O F2 O Fo O F1
- "If we could turn on telomerase activity in all our cells, we could prevent aging" is true or false.A PI in your facility has finished working with his transgenic line of mice and would like you to cryopreserve embryos (freeze them in liquid nitrogen) so that he can keep them for later experimentation without paying the extra cost of a breeding colony. Which of the following steps do you take? Select all that apply: a) Use the van der Lee/Boot and Whitten effect to time mate your females. b) Superovulate your females by injecting with PMSG and hCG. c) Breed the mice with a vasectomized male. d) Collect ova from the ampulla the day you find a plug. e) Collect blastocysts from the uterus 3 days after finding a plug.Give a new example of transgenic organism wherein i can generate desired characteristics of that certain organism
