Describe the main principles of natural selection: 1)Populations evolve, individuals do not
2)Variations occur naturally within a population
3)All species have a capacity to overproduce
4)Adaptations help individuals compete successfully for survival
5)Beneficial adaptations will become more common in a population
6)Species can evolve into new species over many generations of successful adaptations

D. Read the genome sequence to determine the quantity and organization of operons. 

The scientists used the technique to study operons in E. Coli by studying the genome sequence. This sequence would also tell the frequency of occurrence of operons in the sequence and where they are located and in which fashion are they organized. It is important to understand which genes are coupled up in the operon.
