Cloning.
1:22:04
What if I were to tell you that I could take
a scraping of skin from your finger...
1:22:10
..and create another Ezra Lieberman?
1:22:13
I would tell you not to waste
your time on my finger.
1:22:17
Anyway, that is cloning.
1:22:19
It was first done with plants. A cutting
taken from a plant and transplanted...
1:22:24
..grew to be the exact duplicate
of the donor plant.
1:22:27
Now we are doing the same thing
with laboratory animals.
1:22:32
You mean you can produce
an animal from itself?
1:22:35
We take the unfertilised egg
of an ovulating female...
1:22:40
..and destroy all of its genes
and chromosomes.
1:22:43
We then implant the nucleus
of the donor cell,...
1:22:47
..which could be taken from a blood
sample, or even a skin scraping.
1:22:51
That cell,
with its genetic material intact,...
1:22:55
..eventually becomes an embryo
and is born as a living creature.
1:23:01
Without parents?
1:23:02
Well, it has no father
because the egg was never fertilised.
1:23:07
No mother, because its genetic code
comes from another being.
1:23:11
Can you follow that?
1:23:13
And this creature
is an exact duplicate of itself?
1:23:19
Oh, Doctor, how can that be?
1:23:23
Come along.
1:23:30
Our experiments began with the simplest
of animals: shrimps and frogs.
1:23:36
Animals in which the female's eggs
are fertilised externally.
1:23:46
Then we moved on to mammals.
1:23:49
We tried several laboratory animals
and found the rabbit most convenient.
1:23:54
I had to develop instruments
which could accomplish the operation...
1:23:59
..and a whole micro-injection system.
I'll show you how it's done.
