-'Oh, and, Jonathan? While I'm at the
'opticians, can you water my plants,
'mm, feed my fish...? Oh, and would you be a dear and do my laundry?'
-I'll do my best,
but there is only one of me, Ms Hucklebuck.
74, 75, 76,
Whoa, Professor, even by your standards,
this looks pretty bonkers.
It's my new home-made 3-D printer.
I'm using Mr Quackers here to make an army of rubber duckies.
Wow, that's actually pretty impressive.
87, 88, 89...
-Going live in five, everyone.
Ach, I'd better go and do the show.
Come on, everybody!
-It's time for...
Today we're asking, "Is every human being unique?"
The human body is made up of over
37 trillion tiny cells, and almost
every one of them contains the set of instructions for making you.
This instruction manual - or genetic code - is stored in our DNA,
otherwise known as...
Dioxy-pipa-nooky-hooky what now?
Every living thing has DNA in its cells -
Believe it or not, human and chimpanzee DNA
is nearly 99% similar.
'Yeah, for some reason that doesn't surprise me.'
In fact, all human DNA is almost
99.9% similar, and it's only in
the tiny 0.01% where our genetic differences occur.
So there's your answer -
our DNA is always similar, but never exactly the same.
-Well, not quite - there is one exception.
Find out more after this break.
-Maybe just a quick 40 winks.
RUBBER DUCK QUACKS HE SNORES
Oh, better get back to the duckies.
Hup! 105, 106, 107...
-Oh, hey, Colin.
-Yeah, I already said "hello", Colin.
Yeah, I heard you the first time, Colin.
He's very friendly today.
-BELL RINGS COLINS:
So tell us, Dr Knowles, are human beings unique?
There is one exception, and that's
in the case of identical twins.
As we know, each egg or embryo has its own unique genetic code,
but sometimes an egg splits in two.
In this case, the resulting human beings are built using
the exact same instruction manual.
So are they the exact same in every way?
No. Their DNA is the same,
but as they each have different
life experiences, they will develop their
own completely unique traits and personalities.
See you next time!
And we're clear!
you really need to start thinking
these inventions through a bit more.
Yeah, you're probably right. All the same, though,
the place is going to be very clean.
Oh, hello, Jonathan.
How do you like my new spectac...?
I'm seeing double. No, no, no - double-double.
No, no - double-double-triple-double.
-The name's Colin, actually.
It's over, done and dusted! Wa-hey!
