Prior to the work of scientists did not distinguish between members of the archaea and the bacteria.

Carl Woese

Explanation:

Earlier scientists used to divide organisms in two major groups, the prokaryotes which consisted of bacteria and the eukaryotes which consisted of all the other higher organisms. Carl Woese divided organisms in three groups: Bacteria, Archaea and Eukaryotes. He concluded that Archaea are more similar to eukaryotes than to bacteria. Previously Archaea were thought to inhabit only hostile extreme places but now they have also been discovered in other less hostile environment.

Archaea are similar to bacteria when it comes to morphology. But the process of translation and transcription is significantly different from bacteria and resembles eukaryotes more. Their cell membrane have unique ether linked lipids for more stability and they have some unique metabolic pathways like methanogenesis.

answer; i believe its (ovulation);

"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."
