Which of the following are polymers? (there may be more than one correct answer.) Amino acids Nucleotides Proteins Fatty acids Polysaccharides Nucleic acids

Which of the following is true about nucleosides and nucleotides? Choose all that apply. 3 A nucleoside includes only the nitrogenous base. A nucleotide includes a nucleoside + one or more phosphate groups A nucleoside includes a sugar and a phosphate group A nucleoside includes a nitrogenous base and a sugar.

1. Is there more than one way to fold a protein, given the conflicting demands of the different "R" groups and the protein existing in a watery environment? 2. Explain what an R group is. 3. Compare the backbone of a polypeptide with that of a nucleic acid. 4. Proteins perform critical functions in all of our cells. Without proteins, life wouldn’t exist. Think of some specific proteins and describe what function they perform.  5. Explain the difference between secondary and tertiary protein structures.

Correctly order the bond types from strongest (1) to weakest (4) Single Covalent Bond Triple Covalent Bond Double Covalent Bond Hydrogen Bond

Draw the structural formula for adenine and thymine bonded together with hydrogen bonds as they would loook in DNA. draw covalent bonds with solid lines and hydrogen bonds as dotted lines.

How would adding acid to a non-buffered solution be most likely to affect protein structure? Select one: a. Adding acid would disrupt the primary structure of the protein b. Adding acid would cause the protein to become a lipid c. Adding acid would cause the protein to become a carbohydrate d. Adding acid would disrupt the secondary and tertiary structure of the protein
