what are transposons? - ..........ANSWER.......- small segments of
DNA that can move from one chromosome to another
- in both bacteria and eukaryotes
restriction enzymes - ..........ANSWER.......- a special class of DNA cutting
enzymes that exists in many bacteria

make billions of copies in only a few hours
taxonomy - ..........ANSWER.......- the science of classifying living
organisms
- similar organisms are placed in the same taxa (group)
systemics or phylogeny - ..........ANSWER.......- the study of the
evolutionary history of a group of organisms
