Ingram Examined Hemoglobin Structural Variation by Breaking Down the Hemoglobin

question 9

Multiple Choice

Ingram examined hemoglobin structural variation by breaking down the hemoglobin protein into many fragments by chemical treatment and subjecting the fragments to electrophoresis to separate them in a gel; and then in a second dimension, perpendicular to the first, he separated them by chromatography. This two-step approach is commonly referred to as __________.

• A)hybridization
• B)electrophoretic mobility
• C)densitometry
• D)restriction fragment analysis
• E)peptide fingerprint analysis
