Document Summary
Biol 367 chapter 9 dna- protein interactions in bacteria. Recognition helices that lie in the major groove of the appropriate operator. Specificity depends on the amino acids in the recognition helix. X rays are scattered by an object (a crystal) When x-rays interact with an electron cloud around an atom, the x-rays scatter in every direction. However, because x-ray beams interact with multiple atoms, most of the scattered x-rays cancel one another due to their wave nature. The diffracted x-rays are recorded as spots on a detector placed in the path of the x-rays. Temperate phage: phage like lambda that can either lyse the cells or lysogenize the cells. These are lambda c1 homologs in two other temperate phages. Phages like lambda are called temperate phages. These two phages their recognition helices are quite different in that. U can convert the repessor protein for this phage (top one,
