Double Blind Test
Used in Clinical Trials, this is a method to ensure that any one party cannot improperly influence the test. The product (either in a single strength dosage or in multiple dosages) and the placebo are packaged and given a code name known to only the initiating party. These are then sent to another party who gives the coded packages yet another code name or number, and makes a matrix of the previous name/number to the new name/number. This is then sent to the physician who administers these to the patient. At the end of the test, the physician provides records of which patient received which code name/number product. This is then cross-referenced to the intermediate matrix to determine the original code name/number. The results of the treatment are then correlated to determine the efficacy of the drug.
The structure of DNA as proposed by Watson and Crick. It consists of two right-handed helical polynucleotide chains coiled around the same axis. The two chains are anti-parallel with their 3rd to 5th internucleotide phosphodiester bonds running in opposite directions. Under most conditions, the coiling of the chains is such that if the ends are held still, as in circular DNA or in a large chromosome, the chains cannot be separated except by cleavage of one of the strands
