Here's your shmoop du jour, brought to you by proteins.

00:07

They're just amateur teens who now get paid for...what they do.

00:26

All right -- what is the best conclusion from the data collected from Experiments 1-3?

00:30

And here are the potential answers...

00:36

This question asks for the take-home message of the graphs.

00:39

What's it asking?

00:40

Experiments 1 and 2 show that most proteins have a higher amount of aggregation in older

00:45

animals, hence the increase in fold effect, as shown by the graphs.

00:49

Experiment 3 looks at four specific proteins and comes to the same conclusion.

00:53

The first graph in figure 2 shows a large difference between young and aged worm insoluble

00:59

protein aggregation. Mmm, doesn't that sound delicious? That's McDo—uh, never mind.

01:03

...which shows that fem worms...these things...have a large amount of aggregation as they get older.

01:08

However, the second graph in figure 2 shows that the amount of aggregation is less in

01:12

aged gon-2 animals...

01:15

...the special mutant worms that live extremely long lives. Wish we could clone those...

01:20

* Therefore the correct answer is B -- all animals show an increase in protein aggregation

01:23

when they age, but the long-living gon-2 animals do not have as much aggregation overall.

01:28

Oh, well, guys. You tried.
