00:03

Here’s your Shmoop du jour, brought to you by blue bands,

00:06

and no, we’re not talking about Rumours-era Fleetwood Mac…

00:09

but just try listening to “Silver Springs” without bawling your eyes out.

00:15

Here’s a passage about a technique used to separate proteins.

00:28

How many proteins are present in sample 1? And here are the potential answers…

00:38

This question seems straightforward enough—it looks like we’re being asked to interpret

00:41

data and show that we know how to read the chart.

00:47

Remember in the passage where it said the control contains 5 proteins?

00:52

Well, looking at the figure, we can see that the control is the first column,

00:56

and that column contains 5 blue bands.

01:00

From this we can pretty well assume that blue bands are proteins.

01:04

As for the question, how many proteins are in sample 1, let’s just look and see.

01:08

Just one. A single, lone protein. All by itself.

01:15

Just like when Stevie Nicks and Lindsey Buckingham broke up.

01:18

Then again, they made their best music around that time.

01:20

So option A it is!
