Show the pictures The Last Judgment and The Second Coming at appropriate times as you teach the children the parable of the sheep and the goats from Matthew 25:31â46. (For suggested ways to teach the scripture account, see âTeaching from the Scriptures,â p. vii.)
Determination of Protein Secondary Structure by Circular Dichroism: Secondary structure can be determined by CD spectroscopy in the far-UV spectral region (190-250 nm). At these wavelengths the chromophore is the peptide bond, and the signal arises when it is located in a regular, folded environment.Alpha-helix, beta-sheet, and random coil structures each give rise to a characteristic shape and magnitude of CD spectrum.This is illustrated by the graph to the right, which shows spectra for poly-lysine in these three different conformations.etermination of Protein Secondary Structure by Circular Dichroism: Secondary structure can be determined by CD spectroscopy in the far-UV spectral region (190-250 nm).

The three-dimensional shape of a protein is determined by its primary structure. The order of amino acids establishes a protein's structure and specific function. The distinct instructions for the order of amino acids are designated by the genes in a cell. When a cell perceives a need for protein synthesis, the DNA unravels and is transcribed into an RNA copy of the genetic code.
