Ovalbumin, the major protein of egg white, is secreted by cells that line the oviduct as the bird egg moves down the oviduct. Imagine you're repeating the classic Weintraub- Groudine experiment, but with a twist: You're assaying the DNase sensitivity of the promoter regions of the fi- globin and ovalbumin genes in oviduct cells of laying hens. In this case you expect to find that
A) the fi- globin and ovalbumin promoters are equally resistant to DNase treatment. B) the ovalbumin promoter is much more sensitive to DNase treatment. C) the fi- globin promoter is much more sensitive to DNase treatment. D) the fi- globin and ovalbumin promoters are equally sensitive to DNase treatment.
