Question
Chapter 26, Problem 26.89P
Interpretation Introduction
Interpretation:
The method by which scientists restore memory in mice is to be explained. An explanation is to be stated corresponding to the fact that the theory about epigenetics and cognitive memory is supported by the methods through which scientists restore memory in mice.
Concept Introduction:
The changes that occur in DNA but not shown in the actual base sequence are known as epigenetic changes. The epigenetic changes are permanent in nature and transfers from parent to children.
