-BELL RINGS -'Oh, and, Jonathan? While I'm at the | 0:00:02 | 0:00:04 | |
'opticians, can you water my plants, | 0:00:04 | 0:00:07 | |
'mm, feed my fish...? Oh, and would you be a dear and do my laundry?' | 0:00:07 | 0:00:11 | |
-HE SIGHS -I'll do my best, | 0:00:11 | 0:00:13 | |
but there is only one of me, Ms Hucklebuck. | 0:00:13 | 0:00:15 | |
74, 75, 76, | 0:00:15 | 0:00:19 | |
77, 78... | 0:00:19 | 0:00:21 | |
Whoa, Professor, even by your standards, | 0:00:21 | 0:00:24 | |
this looks pretty bonkers. | 0:00:24 | 0:00:26 | |
It's my new home-made 3-D printer. | 0:00:26 | 0:00:28 | |
I'm using Mr Quackers here to make an army of rubber duckies. | 0:00:28 | 0:00:31 | |
HE LAUGHS | 0:00:31 | 0:00:32 | |
Wow, that's actually pretty impressive. | 0:00:32 | 0:00:35 | |
87, 88, 89... | 0:00:35 | 0:00:38 | |
-BELL RINGS -Going live in five, everyone. | 0:00:38 | 0:00:41 | |
Ach, I'd better go and do the show. | 0:00:41 | 0:00:44 | |
-ANNOUNCER: -'Stand by!' | 0:00:57 | 0:00:59 | |
Come on, everybody! | 0:00:59 | 0:01:01 | |
-BOTH: -It's time for... | 0:01:04 | 0:01:06 | |
Today we're asking, "Is every human being unique?" | 0:01:08 | 0:01:12 | |
The human body is made up of over | 0:01:12 | 0:01:14 | |
37 trillion tiny cells, and almost | 0:01:14 | 0:01:17 | |
every one of them contains the set of instructions for making you. | 0:01:17 | 0:01:21 | |
This instruction manual - or genetic code - is stored in our DNA, | 0:01:21 | 0:01:25 | |
otherwise known as... | 0:01:25 | 0:01:28 | |
Dioxy-pipa-nooky-hooky what now? | 0:01:29 | 0:01:32 | |
Every living thing has DNA in its cells - | 0:01:32 | 0:01:35 | |
humans, bacteria, | 0:01:35 | 0:01:38 | |
apples, chimpanzees... | 0:01:38 | 0:01:40 | |
Chimpanzees? | 0:01:40 | 0:01:41 | |
Believe it or not, human and chimpanzee DNA | 0:01:41 | 0:01:44 | |
is nearly 99% similar. | 0:01:44 | 0:01:46 | |
'Yeah, for some reason that doesn't surprise me.' | 0:01:46 | 0:01:49 | |
Ooh-ooh-ooh... | 0:01:49 | 0:01:51 | |
In fact, all human DNA is almost | 0:01:51 | 0:01:54 | |
99.9% similar, and it's only in | 0:01:54 | 0:01:56 | |
the tiny 0.01% where our genetic differences occur. | 0:01:56 | 0:02:01 | |
So there's your answer - | 0:02:03 | 0:02:04 | |
our DNA is always similar, but never exactly the same. | 0:02:04 | 0:02:08 | |
-Well, not quite - there is one exception. -Huh? | 0:02:08 | 0:02:12 | |
Find out more after this break. | 0:02:12 | 0:02:14 | |
-HE SIGHS -Maybe just a quick 40 winks. | 0:02:16 | 0:02:20 | |
RUBBER DUCK QUACKS HE SNORES | 0:02:20 | 0:02:22 | |
Oh, better get back to the duckies. | 0:02:22 | 0:02:24 | |
Hup! 105, 106, 107... | 0:02:24 | 0:02:27 | |
-Hello, McCork. -Oh, hey, Colin. | 0:02:27 | 0:02:30 | |
108, 109... | 0:02:30 | 0:02:31 | |
-Hello, McCork. -Yeah, I already said "hello", Colin. | 0:02:31 | 0:02:35 | |
110, 111... | 0:02:35 | 0:02:37 | |
Hello, McCork. | 0:02:37 | 0:02:38 | |
Yeah, I heard you the first time, Colin. | 0:02:38 | 0:02:41 | |
He's very friendly today. | 0:02:41 | 0:02:42 | |
-BELL RINGS COLINS: -Positions, everyone! | 0:02:42 | 0:02:44 | |
Crumpets! | 0:02:44 | 0:02:46 | |
So tell us, Dr Knowles, are human beings unique? | 0:02:51 | 0:02:54 | |
There is one exception, and that's | 0:02:54 | 0:02:56 | |
in the case of identical twins. | 0:02:56 | 0:03:00 | |
As we know, each egg or embryo has its own unique genetic code, | 0:03:00 | 0:03:04 | |
but sometimes an egg splits in two. | 0:03:04 | 0:03:06 | |
In this case, the resulting human beings are built using | 0:03:06 | 0:03:10 | |
the exact same instruction manual. | 0:03:10 | 0:03:12 | |
So are they the exact same in every way? | 0:03:12 | 0:03:15 | |
No. Their DNA is the same, | 0:03:15 | 0:03:17 | |
but as they each have different | 0:03:17 | 0:03:19 | |
life experiences, they will develop their | 0:03:19 | 0:03:22 | |
own completely unique traits and personalities. | 0:03:22 | 0:03:25 | |
HE GRUNTS | 0:03:27 | 0:03:29 | |
See you next time! | 0:03:30 | 0:03:32 | |
And we're clear! | 0:03:32 | 0:03:34 | |
-COLINS CHATTER -OK, Professor, | 0:03:34 | 0:03:36 | |
you really need to start thinking | 0:03:36 | 0:03:38 | |
these inventions through a bit more. | 0:03:38 | 0:03:40 | |
Yeah, you're probably right. All the same, though, | 0:03:40 | 0:03:43 | |
the place is going to be very clean. | 0:03:43 | 0:03:45 | |
Oh, hello, Jonathan. | 0:03:45 | 0:03:46 | |
How do you like my new spectac...? | 0:03:46 | 0:03:48 | |
Ooh! Oh! | 0:03:48 | 0:03:50 | |
I'm seeing double. No, no, no - double-double. | 0:03:50 | 0:03:53 | |
No, no - double-double-triple-double. | 0:03:53 | 0:03:56 | |
-SHE GROANS -Jonathan! | 0:03:56 | 0:03:58 | |
-ALL: -The name's Colin, actually. | 0:03:58 | 0:04:00 | |
COLINS BICKER | 0:04:00 | 0:04:02 | |
It's over, done and dusted! Wa-hey! | 0:04:12 | 0:04:15 |
