4b,e,f and 6b Excellent: 5 points Average: 3 points Inadequate: 1 point Accurately predicted amino acid sequence from
RNA No errors 3 or less errors More than 3 errors Explained how the two proteins differed in
number and sequence of amino acids Accurate and detailed comparison of the two
proteins with regard to size and amino acid
composition Adequate comparison of the two proteins with
regard to size and amino acid composition Lacking in either size or amino acid composition

different shapes and chemical properties Clear explanation of relationship between amino
acid sequence and structure and properties of
protein Adequate explanation of relationsip between
amino acid sequence and structure and properties of
