Question

Dr. Morelli investigates how gene activity is regulated within a cell, including what signals switch genes "on" or "off." In general, she is interested in the mechanisms that control gene expression and its effect on behavior and health. Her area of research is called:

Answer 1

Her area of research is called EPIGENETICS.

Epigenetics can be defined as the study of the processes involved in the genetic development of an organism, especially the activation and deactivation of genes. It is the study of heritable changes caused by the activation and deactivation of genes without any change in DNA sequence.

Answer 2

The correct answer is epigenetics

Epigenetics is a term referred to as extra genetic information that, with the help of chromatin and DNA modifications, helps or inhibits certain genes. Gene expression follows an order: DNA-> RNA (transcription) -> Protein.

Epigenetics consists of modifications of the genetic functions that are inherited, but which in turn do not alter the individual's DNA sequence. As all cells in the body contain the same genes, epigenetics serves as a means of controlling the functions of each gene, according to the cell.
