CCC: Structure & Function

In 2006, Roger Kornberg was awarded the Nobel Prize in Chemistry for using the X-ray crystallography to determine the 3-D shape of RNA polymerase II protein, which binds to the DNA double helix and synthesizes RNA.

Results: Using data from X-ray diffraction patterns, as well as amino acid sequence determined by chemical methods, researches built a 3-D model of the complex with the help of computer software.

Conclusion: Analysis of the model led to a hypothesis about the functions of different regions of RNA polymerase II protein.

1

Use evidence from the model to identify elements of secondary structure in the RNA polymerase II protein.

1

Make a claim predicting the characteristics of the amino acids located at the part of the RNA polymerase II protein that binds with DNA.

Given that the function of egg yolk is to nourish and support the developing chick, specifically explain why egg yolks are so high in fat, protein, and cholesterol.

This diagram shows a protein embedded in the phospholipid bilayer of the membrane.  Portions of the protein extend into the extracellular and cytoplasmic sides of the membrane.

1

Which characteristic best describe the side chains in the part of the protein in contact with the phospholipid tails of the membrane?

1

Predict what would happen if the side chains that are in contact with the phosopholipid tails of the membrane were to be replaced with the amino acids serine and threonine.

3

After a cow is given antibiotics to treat a bacterial infection, a vet gives the animal a drink of 'gut culture' containing various prokaryotes. Why is this necessary? Use evidence from the diagram to explain.
