Next, students read some background on DNA, genomes, chromsomes, prokaryotes, and eukaryotes, and answer some questions based on the reading. Then, students create models of bacterial and fruit fly chromosomes using string, paper, markers, and tape. Finally, they answer conclusions questions about their models.A.
