The nucleus of an intestinal cell of a tadpole (baby frog) is transferred to an egg whose nucleus has been removed (nuclear transplantation); some of the eggs will develop into normal tadpoles. this
a) that intestinal cells are not differentiated
b) that frogs have large eggs
c) that differentiated cells have retained all of their genetic potential
d) that intestinal cells are embryonic stem cells

C)

Explanation:

Based on the information provided within the question this demonstrates that differentiated cells have retained all of their genetic potential. This can be said because only be retaining their full genetic potential would the eggs be able to develop into normal tadpoles, otherwise they would die out because they lack the requirements needed to develop.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
