Question
Chapter 26.1, Problem 2AQTC
Summary Introduction
To determine:
Pros and cons of altering the genes of a baby.
Introduction :
When a baby’s genes are altered by removing or including a gene in its genetic makeup, then the baby is termed as a designer baby. By this process, any gene associated with the disease can be removed and any gene related to a beneficial trait can be included.

Cloning is the process of creating genetically identical organisms. One simple method of cloning is called artificial embryo twinning. In this process, an early stage embryo is separated into two groups of cells. Each group of cells is then allowed to develop. The embryos are then implanted into the surrogate mother. Each embryo is genetically identical to the other. Some pregnancies in humans have a similar result.
Explain how identical twins are formed.
Compare and contrast the natural formation of identical twins to the artificial embryo twinning process.
Explain how the formation of identical twins or the process of artificial embryo twinning differs from the formation of fraternal twins.
What are some of the major impediments to genetically modifying human embryos?
Is it moral to do stem cell research on embryos? Cite moral and ethical reasons, can you give an alternative?

- Embryonic stem cells used for research most commonly come from: A) an embryo created in a fertility clinic and legally released for scientific research B) an embryo that is approximately four to six days past fertilization C) the embryoblast layer of an embryo in the blastocyst stage D) all of the abovearrow_forwardA 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.

- A couple has a young child who needs a bone marrow transplant. They propose that preimplantation screening be done on several embryos fertilized in vitro to find a match for their child. What do they need to match in this transplant procedure? The couple proposes that the matching embryo be transplanted to the mother’s uterus and serves as a bone marrow donor when old enough. What are the ethical issues (if any) involved in this proposal?arrow_forwardDo you feel CRISPR or other technologies are appropriate for use in human embryo’s? Why or why not?

- what are the main concern of using embryonic stem cellsarrow_forwardDo 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.arrow_forwardGenetic mutations can provide insights into the mechanisms of complex cellular or developmental processes.

- eve stripe 2 reporter A B Hunchback C D 6999 Kruppel E F D In the early Drosophila embryo, the even-skipped (eve) gene is expressed in a striped pattern. eve stripe #2 expression is controlled by a regulatory DNA sequence that includes binding sites for the regulatory proteins Hunchback and Kruppel. The boxed figure at left above shows the expression patterns, in the early embryo, of a reporter gene joined to the eve stripe 2 regulatory sequence, and of the Hunchback and Kruppel proteins. Which of the figures at right best predicts the expression pattern of the eve stripe2 reporter (blue) in a mutant embryo lacking the Kruppel protein? The dashed lines in each outline the eve stripe 2 position in a wild-type embryo.arrow_forwardWhy should changing the genome of human embryos ( human germline gene editing) not be allowed? Please use images provided as helparrow_forwardAnother way to study the role of proteins (e.g., transcription factors) that function in development is to microinject the mRNA that encodes a protein, or the purified protein itself, into an oocyte or embryo, and then determine how this affects the subsequent development of the embryo, larva, and adult. For example, if Bicoid protein is injected into the posterior region of an oocyte, the resulting embryo will develop into a larva that has anterior structures at both ends. Based on your understanding of the function of each developmental gene, what would be the predicted phenotype if the following proteins or mRNAs were injected into normal oocytes? A. Nanos mRNA injected into the anterior end of an oocyte B. Antp protein injected into the posterior end of an embryo C. Toll mRNA injected into the dorsal side of an early embryoarrow_forward
