Database Exam Questions

   

One aspect of Bioinformatics concerns itself with the storage, organisation, and retreival of biological information. The questions in this section consider the contents and use of some of the key abstractions (sequences, structures, graphs ...) that we deal with, and the databases we store them in.

In the excerpt from the PDBsum database shown here, please comment briefly on the following points. Questions correspond to the numbers shown on the image. The region within the circle is an enlargement of the original, for better legibility.             (5.1) What is the relationship between PDBsum and the database linked from this button ("PDB")? (5.2) What do these terms mean and what use can you make of this information when you analyse the structure ("Resolution", "R-Factor", "R-free") ? (5.3) What is the purpose of the database linked from this button and what use can you make from its contents when you analyse the structure ("CATH")? (5.4) What is this information and what use can you make of it ("Residue interactions: * with DNA + with ligand")? (5.5) What is this sequence and why is it here ?
