. In Figure 12.14, why do the nuclei resulting fromexperiment 2 contain different amounts of DNA?
Neema wants to determine whether or not the nucleus of a cell differs in the chemical compounds they contain or not from species to species. She is planning on working with the nucleus of a human and the nucleus of a mouse. She has removed all of the DNA from each nucleus, then has selected and isolated one DNA fragment from each species. What results can Neema expect if she takes the human DNA fragment and inserts it into the mouse nucleus and then inserts the mouse DNA fragment into the human nucleus? Use your knowledge of DNA replication to answer.
In the Hershey–Chase experiment, the radioactive label 32P was present inside bacterial cells (i.e., in the pellet), whereas the radioactive label 35S waspresent outside bacterial cells (in the supernatant). What would the researchers have concluded had the reverse been true, that is, if the radioactive label 35S were inside the cells and the radioactive label 32P were outside the cells?

O A) The bacterial colony was derived from one initial cell that was resistant to infection by the bacteriophage. O B) The bacterial colony was made up of many cells that became resistant to bacteriophage infection independently. O C)A colony formed when a bacterial cell was not resistant to bacteriophage infection. O D) The bacterial cells that made up a colony were resistant to antibiotic.
