Question

Dolly the Sheep, was born in 1996 in Scotland.  She was the first mammal ever cloned from a single cell.  The scientist created Dolly in a lab using three mothers:  Sheep A provided the egg, Sheep B provided the DNA, and Sheep C carried the embryo to term.  During this process, Dolly’s cells went through several phases of mitotic growth. Which statement represents the processes of both the somatic cell cycle and cell differentiation?Group of answer choicesA student scratches his arm causing skin cells to fall off. These cells are soon replaced by identical ones and the student does not notice.A baby is growing in its mother’s womb from a tiny ball of cells to an 8lb baby boy.Hematopoietic stem cells (HSCs) turn into different blood cells in a girl’s hip bone.A teenager undergoes a growth spurt one summer.

Answer 1

These options showed mitotic division only.

A student scratches his arm causing skin cells to fall off. These cells are soon replaced by identical ones and the student does not notice.

A teenager undergoes a growth spurt one summer.

These options showed mitotic division and cell differentiation.

A baby is growing in its mother’s womb from a tiny ball of cells to an 8lb baby boy. >> From a zygote with three germ layers of cells to cells with different functions grouped to become tissue to organ and organ system.

Hematopoietic stem cells (HSCs) turn into different blood cells in a girl’s hip bone. >> From an undifferentiated cell to a specialized cell.
