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.
Nuclear Radiation. There are three primary radiation types associated with radioactivity. Radioactivity is the spontaneous emission of energy from the nucleus of certain elements, most notably uranium. There are three forms of energy associated with radioactivity; alpha, beta and gamma radiation.The classifications were originally made according to the penetrating power of the radiation, see figure 2.uclear Radiation.
