Multiple, fully folded protein chains interacting with each other is a

• primary structure

• secondary structure

• tertiary structure

• quaternary structure

Polymer's split apart to form ________, by __________.

• monomers, hydrolysis

• monomers, dehydration synthesis

• amino acids, hydrolysis

• amino acids, dehydration synthesis

How do phospholipids interact with water molecules?

• Phospholipids dissolve in water.

• The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract).

• The polar heads interact with water; the nonpolar tails do not.

• Phospholipids do not interact with water because water is polar and lipids are nonpolar.

An unknown molecule contains a sugar and a phosphate group. It is likely what?

• carbohydrate

• protein

• lipid

• nucleic acid

The difference of DNA and RNA is the presence of

• Uracil

• Guanine

• Adenine

• Cytosine
