Document Summary
Genes are not going back and forth. Hypothesis for lateral gene transfer: to acquire coordinated function in the cell as a whole, to prevent damage to mitochondrial chloroplast dna from reactive oxygen species (ros). The flow of unpaired electrons leads to formation ros: to generate genetic diversity in a population (nuclear genes participate in sexual recombination, look at the slides. How to detect presence of a specific dna sequence: southern blotting. Probe is a single stranded dna which is complimentary to the dna sequence in your gene. This will create a black mark and then you can see if there is the presence of that gene. Not all genes code for proteins, a lot just code for rna. It only codes for 12 proteins but has 37 genes. Note: you need to know what the organisms look like in real life. Mitochondrial diseases: there are a lot.
