Question

Quizplus · Accepted Answer

This is nuclear transplantation, also known as somatic cell nuclear transfer, a technique used in cloning. The nucleus of the egg cell is replaced with the nucleus of an adult cell, and the resulting embryo contains the genetic material of the donor cell. DNA replacement could be interpreted as a broader term that could apply to many different types of genetic engineering, while nuclear replacement is not specific enough to describe the unique process of nuclear transplantation. Hormonal replacement therapy is a medical treatment unrelated to this kind of genetic manipulation.
