Question 19

(Multiple Choice)

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.
