Enovid is a combined oral contraceptive and the first one of its kind to be approved by the FDA. Enovid uses a combination of two steroids, specifically mestranol and norethynodrel. Answer the questions below about the structures of mestranol and norethynodrel. Which functional group contains the bond labeled A? Which functional group contains the oxygen atom labeled B? Which functional group contains the oxygen atom labeled C? Which functional group contains the oxygen atom labeled D? There are two lone pair electrons on the oxygen atom labeled B. What orbitals do these lone pair electrons reside in? There are two lone pair electrons on the oxygen atom labeled D. What orbitals do these lone pair electrons reside in? What is the electron pair geometry of the oxygen atom labeled C? What is the bond angle at the oxygen atom labeled B? Which of the following below best represents the orbital overlap of the C-C σ-bond labeled E? Which of the following below best represents the orbital overlap of the C-C π-bond labeled E?

Twо mutаtiоns thаt аffect plaque mоrphology in a particular phage (a– and b–) have been isolated. Phages carrying both mutations (a–b–) are mixed with wild-type phage (a+b+) and added to a culture of bacterial cells. Following infection and lysis, samples of the phage lysate are collected and cultured on bacterial cells. The following numbers of plaques are observed: Plaque Phenotype Number a+b+ 2043 a+b- 320 a-b+ 357 a-b- 2134 What is the frequency of recombination between the a and b genes?
