Question

2. Gel analysis practice 1) Label in the below picture and indicate the size of each DNA fragments of samples A, B,C. samples B Marker A 1,200 bp 1,000 bp 900 bp 800 bp 700 bp 600 bp 500 bp ||||||||| | | 400 bp 300 bp 200 bp 100 bp

Answer 1

2) The DNA from crime scene and those of the suspects are taken and RFLP analysis is done to find out a pattern of the RFLP, as they vary in different individuals. If the pattern of RFLP from the crime scene matches with the RFLP of any of the suspect, this proves that , that particular suspect was at the crime scene. In the given figure the RFLP pattern after gel electrophoresis from the crime scene matches with the RFLP pattern of that of suspect 2, while for suspect 1 and 3, the RFLP pattern is quite different than that obtained from the crime scene. So, it can be said that suspect2 was at the crime scene.
