Globular proteins  - usually with hydrophobic interior, hydrophilic surface. 1.   Protein structure  (determines protein function). For example:    “P53 protein”  is a DNA-binding protein  (and is important in  coordinating repair of  damaged DNA). The shape of the P53 protein  recognizes and binds to  specific sequences of DNA.

2.    UV absorbance measurements provide a way to measure  protein, DNA and RNA concentrations. Beer’s law: absorbance extinction  coefficient  path  length conc. Beer’s law says  “absorbance is proportional to concentration”. Remember to label answers with units.
