Questions and Answers

Why is quaternary structure important in regulating the biological activity of certain oligomeric proteins?

  • To favor selection for different combinations of subunits to carry out related functions (correct)
  • To allow for efficient selection of entirely new monomeric proteins
  • To allow different proteins to share the same subunits
  • To duplicate the function of monomeric proteins
  • Why does evolution favor selection for different combinations of subunits in proteins?
