Welcome to the Conceiving a Clone Science Lab
Here you will be performing your own cloning experiment using
the Roslin Institute's nuclear transfer technique.

The lab is ready. Click here to begin.
Step 1: You need to remove the nucleus of the egg cell.
Drag the nucleus to the trash.
Step 2: Drag the donor cell to the petri dish
that contains very few nutrients. By starving the
cell, you are forcing it into the suspended state.
Step 3: Drag the donor cell next to the
eunucleated egg.
Step 4: Click on the switch to fuse the
two cells with an electric current. The nucleus of
the donor cell now directs the functions of the egg.
Step 5: The electric shock has caused the
egg cell to begin development. The egg must now be
temporarily placed in a sheep's oviduct, where it
will be allowed to develop for around six days.
Step 6: After about six days, the embryo is ready to be
implanted into the uterus of a surrogate mother. Drag the
embryo to the mother ewe.
You have completed the cloning experiment. Following a
normal length pregnancy, the surrogate mother gives birth
to a lamb who is an exact duplicate of the organism who provided
the donor dells.
