Discuss the three different types of gene mutations (base substitutions, insertion & deletion).

Please describe in detail how insertion, deletion, and base substitution of nucleotides can have a significant impact on genes, and provide three specific examples (actual gene mutations, not chromosome mutations) of ways in which a very small change in DNA can have a major impact on an organism, and describe each mutation in detail.

Prokaryotic Genetic Recombination and Types of Operons

Discuss the two different types of operons found in bacterial genomes (inducible operons and repressible operons) and describe how they work.

Then, describe the following three different forms of prokaryotic genetic recombination: conjugation, transformation, and transduction.

Hypothesize how recombination might adversely affect the functioning of an operon such as the lac operon or the trp operon. What might be the metabolic implications for an E. coli cell that experiences a disruption of one of these operons?
