Textbook Question
Chapter 16, Problem 7QP
Researchers are learning how to transfer sperm-making cells from fertile male mice into infertile male mice in the hopes of learning more about reproductive abnormalities. These donor spermatogonia cells have developed into mature spermatozoa in 70% of cases, and some recipients have gone on to father pups (as baby mice are called). This new advance opens the way for a host of experimental genetic manipulations. It also offers enormous potential for correcting human genetic disease. One potentially useful human application of this procedure is treating infertile males who wish to be fathers.
- a. Do you foresee any ethical or legal problems with the implementation of this technique? If so, elaborate on the concerns.
- b. Could this procedure have the potential for misuse? If so, explain how.

A controversial issue, closely related to cloning, that has caused a lot of debate is the use of embryonic stem cells. One possible application of these cells is that they may be able to supply replacement tissues to treat diseases such as Parkinson's disease, diabetes, paralysis due to spinal cord injuries, and other degenerative diseases. The word "embryonic", has caused fierce opposition to this type of research because embryos are destroyed when the stem cells are removed. Questions that have surfaced in this debate include: When a cell nucleus is transferred to another cell, have we created life? Does a stem cell have the same status as a human? What should be done with the embryos that are leftover at in vitro fertilization (IVF), clinics? Advocates argue that the medical benefits of stem cell research would be enormous. Opponents argue that life begins at conception and thus this type of research is abortion.

Preimplantation genetic testing for aneuploidy (PGT-A) is meant to identify and discard embryos with chromosome number abnormalities. However, it has not been proven to be valuable in human IVF. What do you think PGT-A is not working as expected
Is it acceptable or not to edit the genome of human embryos to treat genetic diseases?
There is a group of genetic disorders that cause fatal childhood diseases. To avoid having children with these genetic disorders, some parents choose to use a procedure called in vitro fertilization (IVF) followed by genetic testing. Typically, in the first step of IVF, women receive hormone injections to produce multiple eggs, after which the eggs are harvested. The eggs are then fertilized by sperm in a petri dish to make embryos, which are then transferred to a woman's uterus. If the goal is to identify embryos that do not have specific genetic conditions, doctors would screen the embryos before they are implanted into the woman - in other words, they would analyze the embryos' DNA to look for variants of the gene(s) that cause the genetic disorder. While the genetic testing of IVF-produced embryos has been done for decades, the procedure is controversial. The controversies include worries that…

Are they used for similar means…etc. Once you have done that answer the question below. a) There are two types of therapeutic cloning. What are they and how are they different?arrow_forwardA 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.arrow_forwardDo a few cells created by therapeutic cloning of your own somatic cells constitute life?

- For each of the following scenarios, indicate YES (it is cloning) or NO (it is not cloning). 6. ___________ Sperm taken from a male goat is combined with a female's egg in a petri dish. The resulting embryo is implanted into the female's uterus to develop 7. ___________ A sheep embryo, composed of 16 cells, is removed from the mother's uterus and separated into individual cells. Each cell is allowed to multiply, creating 16 separate embryos, which are then implanted in different female sheep to develop to maturity. 8. ___________ A cow with many desirable traits is stimulated with hormones to produce a number of egg cells. Each of these eggs is fertilized and implanted into a surrogate mother. 9. ___________ Cell nuclei from a recently deceased dog are placed into enucleated egg cells from another female dog. These egg cells are then placed into the uterus of an additional female surrogate dog, where it grows into a puppy.arrow_forwardhttps://www.khanacademy.org/science/biology/biotech-dna-technology/dna-cloning-tutorial/a/overview-dna-cloning That is the link for the example ^arrow_forwardIn the reproductive cloning of an animal, what cell type is used as the source of the genome of the cloned animal?

- Woolly mammoths have been extinct for about 4,000 years, but we often find their well-preserved remains in Siberian permafrost. Research groups are now planning to use SCNT to resurrect these huge elephant-like mammals. No mammoth eggs have been recovered yet, so elephant eggs would be used instead. An elephant would also be the surrogate mother for the resulting embryo. The researchers may try a modified SCNT technique used to clone a mouse that had been dead and frozen for 16 years. Ice crystals that form during freezing break up cell membranes, so cells from the frozen mouse were in bad shape. Their DNA was transferred into donor mouse eggs, and cells from the resulting embryos were fused with undifferentiated mouse cells. Four healthy clones were born from the hybrid embryos.

An elephant would also be the surrogate mother for the resulting embryo. The researchers may try a modified SCNT technique used to clone a mouse that had been dead and frozen for sixteen years.

B) Crossover suppression occurs when no recombinant progeny are observed between two genes located within a homozygous paracentric inversion. C) The ends of each chromosome are replicated by an RNA-protein complex called telomerase. D) When a mismatched base pair occurs during DNA replication, mismatch repair corrects the mismatch by replacing the nucleotide on the template strand. E) Mutations occur spontaneously and so may be pre-existing in a population when a selective pressure arises.
