What do all β-barrel transmembrane proteins have in common?
A. The number of β strands.
B. The diameter of the barrel.
C. The number of negative peaks in their hydropathy plots.
D. The general function, i.e. membrane transport.
E. The structural rigidity compared to α-helical transmembrane proteins.
Homework Answers
E. The structural rigidity compared to α-helical transmembrane proteins.
The structural rigidity of β-barrel transmembrane proteins will always higher than the α-helical transmembrane proteins irrespective of their size and length.
α-helical formation of transmembrane proteins is an unstable form because they do not unfold completely within the membranes (the complete unfolding would require breaking down too many α-helical H-bonds in the nonpolar media)

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
