Polymerase stop assays, used to quantify DNA damage, assume single lesions are sufficient to block thermostable DNA polymerase progression. To explore this assumption, 90 base oligonucleotides containing normal or modified DNA bases were amplified using real-time PCR. Data implied that the PCR efficiency was influenced to differing degrees depending on which base lesion was present on the input oligonucleotide; specifically, while reactions with templates containing a single 8-oxo-7,8-dihydro-2í-deoxyguanosine (8-oxodG) were not noticeably altered, the presence of a single 8-oxo-7,8-dihydro-2í-deoxyadenosine, an abasic site, or a cis-syn thymidine dimer (TT dimer) dramatically delayed amplification. In addition, the presence of two tandem 8-oxodGs …

The goal of this lesson is to present the basic scientific knowledge about stem cells, the promise of stem cell research to medicine, and the ethical considerations and arguments involved. One of the challenges of discussing stem cell research is that the field is constantly evolving and the most current information changes almost daily. Few science texts contain stem cell information, and those that do are generally written at a reading level above that of a typical middle grade student. In the lesson, students are introduced to the FIRES strategy and given an opportunity to evaluate stem cell information from …
