Question
Chapter 16.4, Problem 2TYK
Summary Introduction
Introduction:
The epigenetic modifications involve acetylation, phosphorylation, glycosylation, and so on. These changes can take place in the cisternae of the rough endoplasmic reticulum (RER), cytoplasm, or Golgi body. The changes are important as they infer specialization and enzymatic activity to the proteins.

Epigenetics is a HUGE new field in understanding health factors that are transmitted from generation to generation beyond simple genetic inheritance. For example: epigenetic factors contribute to the onset of disease by triggering underlying genetic information. What do you think about that?
Describe a potential strategy for the treatment of epigenetic disease.

- What is the key difference between cis- and trans-epigenetic mechanisms for maintaining an epigenetic modification? We considered genomic imprinting of the Igf2 gene, in whichoffspring express the copy of the gene they inherit from their father,but not the copy they inherit from their mother. Is this a cisora trans-epigenetic mechanism?arrow_forwardWhat are the three kinds of epigenetic mechanisms?arrow_forwardAn epigenetic study of maternal care in mice was used to study transgenerational epigenetic inheritance. This study found that increased maternal care during childhood resulted in lower stress levels as adults and decreased maternal care with their own offspring. Increased maternal care during childhood resulted in lower stress levels as adults and increased maternal care with their own offspring. Increased maternal care during childhood resulted in higher stress levels as adults and decreased maternal care with their own offspring. Increased maternal care during childhood resulted in higher stress levels as adults and increased maternal care with their own offspring.arrow_forward
