One of the peptides that can be recovered after gluten digestion is 33 residues long; 13 of the 33 residues are proline. how many times would you expect proline to appear in this peptide if it were made up of a completely random assortment of the 20 most common amino acids?

It's expected that proline would appear between once or twice.

Step-by-step explanation:

If it were made up of a random assortment of amino acids, each amino acid can have:

chance of being in any particular place in the sequence.

Therefore, Proline has a chance of being in each place.

We've got 33 places,

So if we can multiply the places we've got times the chances and we get:

or 1.65

Therefore it's expected that proline would appear between once or twice.

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
