Chimeric mice can be generated by injecting acell from an early embryo into a blastocyst of another genotype. The fact that the single injected cell can

contribute to many tissues of the chimeric mouse has led to the conclusion that cells of the early embryo are:

(A) differentiated
(B) motile
(C) transformed
(D) transduced
(E) totipotent


The answer is E) Totipotent. It means that one cell, like egg for example has the ability to adjust and grow itself into different types of organs for example depending od the data it receives. Changing the inputted data by injecting a blastocyst with another cell can alter its path of evolution.
