Questions for Discussion section 10. Name_Darren Pinder_____ Due at the beginning of section, 23 July 2009. 1. In no more than two sentences, what is the advantage to a bacterium of a small genome? The advantage of a bacterium with a small genome is the speed at which it can replicate that genome. The smaller the genome, the easier and more quickly it can be replicated as to ensure survival by numbers. 2. How can a bacterial genome (remember, this refers to the genes of a group of very similar individuals, a species) lose a gene? Be brief. When a gene loses its essential need, it is sunken into the genome so as to not be replicated and is ultimately completely lost through time and mutations that delete them.

Unformatted text preview: 3. In no more than two sentences, what is the advantage to a bacterium of a larger genome? Bacteria with large genomes have to take advantage of scant resources which requires more genes to code for the extra metabolic flexibility needed. This however causes a very slow replication speed. 4. How can a bacterial genome (remember, this refers to the genes of a group of very similar individuals, a species) gain a gene? Be brief. Bacteria can pick up genes through lateral gene transfer which is the uptake of DNA from surroundings or other bacteria by a form of copulation known as bacterial conjugation....
