How long are we supposed
to liVe like this?
:41:05
When does
all this gratitude end?
:41:36
( children chattering )
:41:45
- You sure you're okay?
- Yeah.
:41:46
- You sure?
- Yeah.
:41:49
Bye, Mom.
:41:53
- ( door slams )
- ( chatter )
:42:17
( chatter intensifies )
:42:22
- ( screeching )
- Anybody know what this is?
:42:25
It's a big ugly Visual aide.
Let's do it like this.
:42:29
If you think of DNA
as a fuse box,
:42:32
aach of the genes are either
switched on or off,
:42:35
depending on which cell
we're talking about.

for say the length of KeVin's...
:42:43

...nose hair wouldn't be

:42:48

isn't present?
:42:50
No, no, it's present,
it's just inactiVe. It's turned off.
:42:55
It's dead.
