D18S51

  

Penta E

  

 

To match DNA samples from a crime scene, forensic scientists analyze the number of repeats at 16 or more STR loci. Today's technology can measure up to six loci at once. Row A from Handout 2-2 (below) shows the variations at five STR loci for one person. The name of each STR locus is in the gray box. D351358 100 14 1723 118.30 15 1409 122.48 100 120 140 D3S1358 THOI 12 13 19 13 16 19 14 17 20 2463 168.40 9.3 1095 175 26 160 D21511 200 THO1 30 2543 222.87 The first STR locus (D3S1358) is on chromosome 3 where the sequences TCTG and TCTA are repeated 2 to 15 times. Scientists use polymerase chain reaction (PCR) to amplify the DNA that includes this region. The PCR products are separated by size and charted on an electropherogram (or e-gram). The peaks on the left are the smallest DNA fragments (those with fewer repeats). The peaks on the right are the largest (with more repeats). D21S11 Ludmila 0001 24 27 30 35 36 372 133 26 24.2 Nine common variations are found at D3S1358. The allelic ladder e-gram below is not from one person, but shows all the possible variations at each of the five STR loci. Each variation is identified with a number. The person above has variation 14 (shown as the first number in the box below the graph) at the D3S1358 locus on one copy of chromosome 3 and variation 15 on the other. 25.2 31.2 35.2 D18551 39 300 280 15 1445 19 1348 311 27 326 82 300 320 340 D18S51 360 литатлииииии Penta E 011 14 17 20 23 26 9 12 15 18 21 24 27 10 13 16 19 22 25 10.2 400 1550 411 16 13 1420 380 416.09 400 420 440 460 480 Penta E Ellii3 15 17 19 21 2 6 8 10 12 14 16 18 20 22 23
