Now I look closer at that code:

     NSDictionary *tempDict = [baseDefinitions objectForKey: @"A"];
     if ( tempDict != nil  && [tempDict isKindOfClass: [NSDictionary 
class]] ) {
         adenosineRepresentation = [[BCNucleotideDNA alloc] 
initWithSymbol: [@"A" characterAtIndex: 0]];
         [baseDefinitions removeObjectForKey: @"A"];

Why not write this as one line:

adenosineRepresentation = [[BCNucleotideDNA alloc] initWithSymbol:'A'];

I don't understand the function of tempDict, and the removeObjectForKey
