Question

Transplanting the nucleus of an epithelial cell into an egg cell lacking genetic information leads to the formation of

A. another epithelial cell.

B. a dead cell.

C. a normally developing embryo.

D. a hybrid cell that has characteristics of both embryonic cells and epithelial cells.

Answer 1

Transplanting a diploid nucleus from an epithelial cell into an enucleated egg cell typically leads to the formation of a normally developing embryo, as the somatic cell nuclear transfer technique creates a genetically identical zygote to the donor.

Step-by-step explanation:

The technique of transferring a diploid nucleus from an epithelial cell into an enucleated egg cell, known as somatic cell nuclear transfer, is used for the purpose of reproductive cloning. This method creates a new zygote that is genetically identical to the donor of the nucleus. Following this procedure, if done correctly, the zygote is then stimulated to divide and can develop into an embryo, which through further stages of development, can lead to a fully developed organism. By transplanting the nucleus of an epithelial cell into an egg cell lacking genetic information, the result would be option C. a normally developing embryo.
