123. (c) the development of new scientific tools for use in crime detection (Because in the third para the author laments that "These discoveries were of little use in crime detection" and further elaborates the use of Electrophoresis which has made crime detection possible")
124. (c) may be used to help identify those who were present at the time of a crime (Because the first para states that "genetic markers in blood and other bodily fluids may someday prove as useful in crime detection as fingerprints" and subsequently the invention of Electrophoresis is mentioned)
125. (d) indicate that the blood samples received by crime laboratories are not given freely (Because the para three mentions that "Rather than a plentiful sample of blood freshly drawn from a patient" which means blood is not easily or freely available)
126. (b) Can electrophoresis be used to identify genetic markers in saliva? (Because the second para mentions that "genetic markers are present not only in blood but also in other bodily fluids, such as perspiration and saliva")
127. (b) discoloration or staining (Because the third para mentions that "tiny fleck of dried blood of unknown age from an unknown “donor” on a shirt or a scrap of rag that has spent hours or days exposed to air, high temperature, and other contaminants" Here size, passage of time and exposure to heat are taken as destructors of evidence)
128. (a) whether or not a sample of blood could have come from a particular person (Because the first para tells that "genetic markers in blood and other bodily fluids may someday prove as useful in crime detection as fingerprints" i.e, just like fingerprints identify the right person the genetic marker technology will also identify that the blood has come from a particular person)
129. (c) more rapid testing (Because the second last para tells about "cost of a week or more of laboratory time" and the Brian Wrexall's technique "could test for ten different genetic markers within a 24-hour period")
130. (a) I only (Because the "The standard ABO blood typing has long been used as a form of negative identification" and "These discoveries were of little use in crime detection" but not no use and the process of Electrophoresis passes current through the genetic markers)
