The way in which the data that were obtained from the crime that had occurred. Introduction: Short tandem repeats (STRs) are the repeated sequence of one to five nucleotides adjacent to each other in the specific regions of the DNA. These repeats vary highly from one person to another and also the two alleles of the same person may have different STRs. Today, STR is the most widely used genetic marker in forensic science to find out if the suspect is innocent or culprit.

To determine: The suspect who is to be charged of the crime from the obtained data.

Introduction: Polymerase Chain Reaction (PCR) is a technique used to amplify very poor amounts of DNA present in the cell. In this technique, specific primers and polymerase enzymes are added followed by alternate heating and cooling to denature and anneal the DNA fragments. Thus, it plays a vital role in DNA analysis because it produces millions of copies of DNA in a short period of time in a parallel way.

The following shows the results of DNA profiling from a rape case. The evidence sample (S) consists of a mixture of DNA from the victim (V) and the DNA of the rapist(s). DNA is taken from four likely suspects (who were present at the same party as the victim on the night of the crime), Alan (A), Brad (B), Charle (C), and Don (D). The results of typing for two different polymorphic loci are shown. 1)Which person is homozygous for locus 1? A. Alan B. Brad C. Charlie D. Don E. Victim

The key portion of the autoradiograph from a single locus probe analysis of various DNA samples in a rape investigation is shown in this figure. (Please refer to the attached Picture) Samples of DNA were loaded into the following lanes: (based on the picture) known blood sample of victim known blood sample from defendant DNA size markers female fraction from vaginal swab of victim male fraction from vaginal swab of If you are the DNA analyst, you should conclude that: A. The suspect is guilty B. The suspect might be guilty, but more probes should be used. Explain your answer and Provide Conclusion.
