[单项选择] Since the first brain scanner was constructed several years ago, computed tomography (X 线断层摄影术)or computed medical imagery, has become fairly widely used. Its rapid acceptance is due to the fact that it has overcome several of the drawbacks of conventional X-ray technology. To begin with, conventional two-dimensional X-ray pictures cannot show all of the information contained in a three-dimensional object. Things at different depths are superimposed, causing confusion to the viewer. Computed tomography can give three-dimensional information. The computer is able to re- construct pictures of the body’’s interior by measuring the varying intensities of X-ray beams passing through sections of the body from hundreds of different angles. Such pictures are based on series of thin ’’slices’’. In addition, conventional X-rays generally differentiate only between bone and air, as in the chest and lungs. They cannot distinguish .soft tissues or variations in tissues. The liver and pan

[简答题]

You have constructed a plasmid set containing a series of nucleotide insertions spaced along the length of the glucocorticoid(糖皮质激素)receptor gene. Each insertion encodes three amino acids. The map positions of the various insertions in the coding sequence of the receptor gene is as follows. The plasmids containing the receptor gene can be functionally expressed in COS cells(猴肾细胞)，which contain a steroid(类固醇)-responsive gene.
Using these cells, you determine the effect of each of these insertions in the receptor on the induction of steroid-responsive gene and on binding of the synthetic steroid dexamethasone(地塞米松)．The results of these analyses are summarized in the table.
请回答如下问题(用中文回答)：
(1)How many different functional domains does the glucocorticoid(糖皮质激素)receptor have Indicate the position of these domains relative to the insertion map.
(2)Which domain of receptor is the steroid-binding domain
(3)List two methods to determine which domain is the DNA
