The following experiment is designed to study the role of several hormones in the regulation of metamorphosis in frogs.

Group #	Treatment	Days to Metamorphosis
1	Saline	30
2	Prolactin	> 100
3	TSH	15
4	Thyroxine	10
5	Corticosterone	30
6	Thyroxine + Corticosterone	5
7	Prolactin + TSH	30
8	Thyroid gland removed	> 100

 

If the thyroid gland were removed from the tadpoles in Group 4, metamorphosis would

A. SeqA binds to hemimethylated DNA and is required for delaying rereplication.

B. As the origins are hemimethylated they bind to the cell membrane and may be unavailable to methylases.

C. The dat locus contains DnaA-binding sites that titrate availability of DnaA protein.

D. Hda protein is recruited to the replication origin to convert DnaA-ATP to DnaA-ADP.
