3. The chromosomes in the cell nucleus would contain the most radioactivity because thymine is part of the DNA molecule and chromo-somes are composed of DNA. Inclusion/Special Needs Show students a picture of a bacterial cell and an animal cell. Talk about the location of DNA in each cell and where DNA replication occurs.
