The diagrams show different stages of cell division in the somatic cells of a plant. the stages are not shown in order.

First would be prophase, where the nucleus is dissolved. Then comes metaphase, where the chromatin condenses into chromosomes and the chromosomes are lined up in the center. Next is anaphase, in which spindle fibers attach to the telomeres of the chromosomes and separated to opposite ends of the cell. Finally, comes Telophase and Cytokinesis, in which the entire cell pinches apart and two new nuclei are formed around the duplicated chromosomes.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
