GENETIC MUTATION IN THE MICROBIAL WORLD


This is only a summary and you will need to add details from Chapter 10 of Madigan, Martino and Parker, Brock, Biology of Microorganisms, 10th editon. Prentice Hall, publishes.

Recall that the flow of information within a cell involves the transcription of DNA to mRNA and the translation of mRNA to protein. Recall also, that the flow of information between bacterial generations involves DNA replication and distribution to two equal daughter cells.Therefore, we would exect a change in microbial DNA to be replicated and passed on to future generations and to effect protein structure and function if the change occurred in the gene that coded for that protein. In this chapter we take a closer look at the cause and effect of changes in DNA. These changes are called mutations.
