Matching - each choice is used once

Draggable item		Corresponding Item
The part of the amino acid that determines how that amino acid interacts with other amino acids and/or water		a molecule made of amino acids that has folded into a specific 3-D shape whose JOB depends on that shape!
amino acid		building block or monomer of proteins
protein		the sequence of bases in the DNA (in a gene)
The sequence of the amino acids in a protein depends on (is determined by) the ...		the R group

Matching - hint- the colors are the same as we used in class

Draggable item		Corresponding Item
how oppositely charged amino acids (acidic and basic) will behave in a folded protein		yellow hiding on the inside of the folded protein
the positions of hydrophilic amino acids in a folded protein		white facing outward from the protein
how cysteine amino acids that form strong cross-links will behave in a folded amino acid
the positions of hydrophobic amino acids in a folded protein

Click on this link ... scroll down to you see this interactive and click on the 4th box down (see red arrow) to "preview" the interactive
Set up the following...

Then hit the play button - see red arrow - once the protein folds, pause the animation and answer the questions below...

Where did the TRP amino acid(s) end up in the final folded protein?  __________.  Why did the TRP amino acid(s) end up in this part of the protein? __________.  Where did the 

Where did amino acids like GLU or GLN end up? __________  Why?  __________
