When performing COR analysis, the center of rotation offset cannot be greater than ______ pixels.

The Ramp filter is indicated by which of the following?  

The slice labeled B is which of the following:

The overall shape of an image and the background information is most likely found in which of the following areas of this frequency graph?  

What has the greatest influence on protein stability?

A sequence of amino acids in a certain protein is found to be -Ser-Gly-Pro-Gly-.  The sequence is most probably part of a(n):

When a peptide bond is formed, a(n ) group reacts with a carboxylate group.   In the peptide Trp─Ser─Val, valine is at the .   In the tripeptide Trp─Val─Phe, the N-terminal residue is .

Which one of the representations describes the oligopeptide shown below? 

You are trying to separate 2 proteins by gel exclusion chromatography . Listed below is information about each protein.   Molecular Weight pI Protein 1 55 kDa 4.2 Protein 2 22 kDa 8.7 Which protein will elute first from the column? Give a reason for your choice Which other method could you use to separate this proteins? Explain

You have purified a new peptide hormone.  To determine its amino acid sequence you have digested the polypeptide with trypsin and in a separate reaction you have cleaved the polypeptide with cyanogen bromide.    Cleavage with trypsin yielded 5 peptides that were sequenced by Edman degradation as shown in the following.    Ser─Leu Asp─Val─Arg Val─Met─Glu─Lys Ser─Gln─Met─His─Lys Ile─Phe─Met─Leu─Cys─Arg   Cleavage with cyanogen bromide yielded 4 peptides that were sequenced by Edman degradation:   His─Lys─Ser─Leu Asp─Val─Arg─Val─Met Glu─Lys─Ile─Phe─Met Leu─Cys─Arg─Ser─Gln─Met   Determine the sequence of the intact protein.
