Solved in 2 steps
- Explain how epigenetic modifications are involved in developmentalchanges that lead to the formation of specific cell types.Compare and contrast epigenetic changes that are programmedduring development versus those that are causedby environmental agents.“In the early Drosophila embryo, the establishment of different body regionor tissues along, on the one hand, the anteroposterior axis and, on theother, the dorsoventral axis are initiated by clues provided by the egg’smother; however the nature of those signals and the way in which theyoperate is completely different”. Discuss whether this statement is correct.
- Discuss the similarities and differences of phenotypic variations that are caused by epigenetic gene regulation versus variation in gene sequences (epigenetics versus genetics).Define Epigenetic Inheritance Epigenetic inheritance Multiple Choice includes a subset of epigenetlc changes that are passed from parent to offspring across generations. occurs only in female offspring via processes like DNA methy ation is the inheritance of the poténtiol to have DNA changes occur, not the inheritance of actual epigenetic changes is always the result of environmental effects on the cells in an organism involves the inheritance of changes In gene expression thot offects oll traits in an organism Prey 1 of 14 Ne1) using at least one named example discuss the implication of allelic heterogeneity in single gene disorder for the presentation and progession of the disorder and its treatment 2) discuss the importance of understanding epigenetics in improving people health
- Describe the inheritance pattern of maternal effect genes. Explainhow the maternal effect occurs at the cellular level. What are theexpected functional roles of the proteins that are encoded bymaternal effect genes?stion 20 of 20 CO Epigenetics is the study of heritable traits that are not induced by changes to DNA sequence. Epigenetic changes can be inherited during somatic cell division to regulate the daughter cells of an individual organism. Most epigenetic modifications are reset prior to meiosis. However, some epigenetic changes can be inherited across generations. For example, environmental factors such as nutrition and chemical exposure can induce heritable epigenetic changes in animal models (Relton and Davey Smith, 2012). Genome imprinting is one type of epigenetic modification in which a cell or organism can reduce the expression of a gene and thereby silence the gene. Genome imprinting is caused by DNA methylation and histone modification, which reduce expression of a gene. The silencing occurs in a parent-of-origin-specific manner, where either the maternally derived allele or the paternally derived allele is imprinted and silenced. Expression occurs only through the nonimprinted…Explain hoxA3 and HoxD3 genes are nearly equivalent yet they play distinct roles in the development of mouse.
- The following is true about epigenetic gene control: O epigenetic changes to the chromatin may result from childhood development epigenetic changes to the chromatin may result from chemicals in the environment O epigenetic changes to the chromatin may result in cancer O An example of a chromatin change is DNA methylation that prevents gene expression from that area of the DNAEpigenetic Regulation of Learning and Memory: Accumulating evidence suggests that the epigenetic machinery might regulate the formation and stabilization of long-term memory. Answer the following questions: Review and summarize current literature, focusing on the involvement of epigenetic regulation in learning and memory.A rare dominant mutation expressed at birth was studiedin humans. Records showed that six cases were discoveredin 40,000 live births. Family histories revealed that in twocases, the mutation was already present in one of the parents.Calculate the spontaneous mutation rate for this mutation.What are some underlying assumptions that may affect ourconclusions?
