Summary Introduction

To explain:

The epigenetic effects on the children and grandchildren of people who are exposed to famine as children.

Introduction:

Famine is the intense scarcity of food that may lead to death of the people. Famine can be caused by several factors such as population imbalance, crop failure, warfare, and inflation. Famine can induce an epigenetic change in the people who exposed to famine in their early life.

Summary Introduction

To explain:

The types of epigenetic changes in chromatin and phenotypic effects on lipid and cholesterol metabolism.

Introduction:

The study of heritable changes in the gene function, without changing in the DNA sequence is called the epigenetics. Epigenetics mostly involves the change in the chromosome that affect gene expression and its activity. DNA methylation and histone modification, are the examples of such mechanism that produce these epigenetic changes in the gene function.
