Why do some smokers become addicted to nicotine and others do not? And does the tendency to smoke run in families? Researchers are conducting studies on identical twins -- some smokers, some non-smokers -- to help determine the heritability of nicotine addiction. Identical twins have identical genomes, so if one of the twins is a smoker it is likely that the sibling will be a smoker, too. By studying their metabolic reactions to the nicotine, the scientists expect to learn whether addiction is more a matter of character, environment or the gene itself.

All 50 Secrets of the Sequence videos have an accompanying classroom-tested lesson that encourages students to further explore the video topics. Each lesson includes background information, state and national science standards, discussion questions and answers, teacher notes and an activity that will ensure a hands-on, "minds-on" experience.
