______ is a favorite model organism from the early days of genetics. It taught us how to link gene distance and genetic recombination frequencies, body plan development, and molecular mechanisms of learning and memory, just to mention a few.

MCQs on the structure and function of DNA and RNA and how these nucleic acids are used to form proteins, and their importance in genetics and inheritance. Also covers DNA replication, transcription, gene expression, mutation and repair, recombination, molecular techniques, and appropriate molecular models.
