what is the process of this x-ray method?
The technique of single-crystal X-ray crystallography has three basic steps,to obtain an adequate crystal of the material under study;  the crystal is placed in an intense beam of X-rays, usually of a single wavelength; data are combined computationally with complementary chemical information to produce and refine a model of the arrangement of atoms within the crysta
X-ray crystallography
The technique of single-crystal X-ray crystallography has three basic steps. The first—and often most difficult—step is to obtain an adequate crystal of the material under study. The crystal should be sufficiently large (typically larger than 0.1 mm in all dimensions), pure in composition and regular in structure, with no significant internal imperfections such as cracks or twinning.

In the second step, the crystal is placed in an intense beam of X-rays, usually of a single wavelength ("monochromatic X-rays"), producing the regular pattern of reflections. The angles and intensities of diffracted X-rays are measured, with each compound having a unique diffraction pattern. As the crystal is gradually rotated, previous reflections disappear and new ones appear; the intensity of every spot is recorded at every orientation of the crystal. Multiple data sets may have to be collected, with each set covering slightly more than half a full rotation of the crystal and typically containing tens 
dna that contains genes from more than one source is called UNANSWERABLE what does 'gene' means? A sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein what is its purpose? The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic trait. what are some of the essential ones? Housekeeping genes what is its regulation? A cell regulates its gene expression depending on its external environment, its internal environment, and its specific role if in a multicellular organism can it mutate? Yes what common thing does the housekeeping ones have in humans? UNANSWERABLE what is the cell cycle in the housekeeping ones? The Rho-related genes are important in nuclear trafficking as well as with mobility along the cytoskeleton in general the later gene product that you mentioned earlier, does it interact? Yes, proteins can interact with many types of molecules, including with other proteins, with lipids, with carboyhydrates, and with DNA. how can you determine its form? X-ray crystallography, one of the major structure determination methods
