1:21:01
Well, some people would say
that's a perfect definition of a scientist.
1:21:08
What exactly do you mean when you say
the boys you saw were more than twins?
1:21:14
Not only did they look alike but
they were also very alike in personality.
1:21:20
That is unusual.
1:21:22
Twins who are separated at birth
develop totally different personalities.
1:21:27
But these twins, or perhaps
I should say triplets,...
1:21:31
..because I believe
my associate saw another,...
1:21:34
..were like the same people,...
1:21:37
..but brought up with different languages.
1:21:42
It's impossible, of course.
1:21:46
Excuse me, Doctor,
but what is impossible?
1:21:53
What is impossible, Doctor?
1:21:56
Mononuclear reproduction.
1:21:59
Oh... Doctor...
1:22:02
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.
