Fill in the blanks: A polymer is a large (term for large molecule) that is composed of repeating subunits called
Given these two amino acid monomers, show the resulting peptide bond that would form after a dehydration reaction.
List three differences between DNA and RNA.
Explain why the base-pairing rules exist. Why, exactly, must adenine base-pair with thymine, and guanine base-pair with cytosine?
Match the macromolecule with its function:
Choose the correct term: If a protein's primary sequence had a bunch of hydrophilic amino acids, you would expect them to hide from/face toward water.
Choose the correct term: When you digest starch,dehydration/hydrolysis enzymes work at breaking up the starch polymer.
Hemoglobin is the protein in red blood cells that carries oxygen throughout the circulatory system. The hemoglobin molecule is made up of four total protein chains (four subunits) clumped together. Two of the protein chains (the alpha subunits) are made of 141 amino acids each. The other two proteins (the beta subunits) are made of 146 amino acids each. Based on this information, which of the four levels of protein structure is described?
