Homework Answers
- Epigenetics is the study of heritable phenotype changes which do not involve alterations in the DNA sequence. They are also referred as the features that are "on top of" or "in addition to" the traditional genetic basis for inheritance.
- Epigenetic transgenerational inheritance of disease susceptibility is usually induced by ancestral exposure to several different environmental toxicants . This can be carried forward from parent to their offsprings at the initial stages of development.
- Epigenetic modifications are reversible modifications on a cell's DNA or histones which in turn affect gene expression without altering the DNA sequence. In many cases, demethylation can take place to allow for "epigenetic reprogramming."
