Thanks, that is helpfull in clearing up some of my problems.  Unfortunately, 
this is just a "topics" class and not one that goes into the sort of detail 
that I would like to see in a science class.  So I have neither a molecular 
biology or microbiology book.  I must say though, that the class has my 
interest peaked. I hadn't considered biology as a major since highschool, 
but have considered it since starting this class. (currently working toward 
a business degree)
