Question

Female bees develop into either queens or workers. Queens and workers are different in size, anatomy, and behavior, but queens and workers develop from identical eggs. The difference is caused by their food: larvae that eat royal jelly develop into queens, while larvae that eat normal food develop into workers. While the mechanism of royal jelly's effects on bee development is not completely understood, one result of eating royal jelly is a reduction in the transcription of Dnmt3, which encodes a cytosine methyltransferase. 2nd attempt See Hint Which of the following are consequences of bee larvae eating royal jelly? Choose one or more: O A. More histones are methylated. OB. Fewer histones are methylated. C. More DNA is methylated. OD. Less DNA is methylated. E. Expression of many other bee genes is increased. OF. Expression of many other bee genes is reduced.

Answer 1

Transcriptional activators:

1. CRP

2. Acetylated histone

3. TFIID

4. GAL4

5. Thyroid hormone receptor

RecA protein has multiple activities, all of which are related to DNA repair. It is not involved in transcriptional activation.

Hope this answer helps.
