- Homeotic genes are genes that ________. activate and inactivate other genes code for important cellular proteins such as actin and myosin are only transcribed during the first4 hours of embryonic development are only found in vertebratesThe sequence of genes in a hypothetical animal cell is normally A-B-C-D. This results in normal development. Due to a mutation, the genes change position (A-C-D-B) resulting in abnormal development. This research was originally conducted and verified by which biologist?The subject: forensic biology; about forensic anthropology Question: Further Research A smooth (gracile) skull of a female appears quite different from the bumpy (robust) appearance of the male skull. What causes the male skull to be thicker with more dense bone? Research the effect on bones of each of the following: a. XX or XY chromosomes b. Production of higher levels of testosterone in males c. Effect of larger muscle mass on bones After researching these factors, form a hypothesis toaccount for the differences in the adult male and female skulls.
- Exposing C. elegans to an RNAi molecule homologous to a non-protein-coding RNA gene resulted in the worms’ inability to respond to touch. What predictions could you make about the function of that gene in development?What changes, if any, would you predict would occur in the pigmentation of Drosophila melanogaster with increased global warming? What type of genetic changes would you expect to see? Be as specific as you can.What group of proteins play a key role in controlling the program of developmental changes? motor proteins transporters transcription factors restriction endonucleases cyclins
- Which statement about Hox genes is false? a. They are expressed in similar patterns in the embryos of both mice and flies. b. They include a conserved region of base pairs called the homeobox. c. They are arranged in similar clusters of genes in both mice and flies. d. They are part of the so-called genetic toolkit. e. Because of their important functional roles, they evolved rapidly in both mammals and flies.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. Based on what you have read, explain why you are for or against stem…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…
- Mammography is an accurate screening technique for the earlydetection of breast cancer in humans. Because this techniqueuses X rays diagnostically, it has been highly controversial. Canyou explain why? What reasons justify the use of X rays for sucha medical screening technique?Considering that you manipulated a zebrafish embryo by injecting high levels of retinoic acid so that no anterior genes will be expressed. Surprisingly, after embryonic development, you are still able to observed the presence of anterior structures. What could explain this observation, does this mean any errors has been committes( provide a specific answer or postulatiom of why it happened)? What changes in your experiment would you make to achieve your objective?Another 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 embryo
