05:14:40,428 --> 05:14:42,663 SEE WHAT THE CODING CAPACITY OF 7670 05:14:42,730 --> 05:14:44,432 THIS IS, THEN YOU LOOK AT THE 7671 05:14:44,498 --> 05:14:46,434 TUMOR OR SOMETHING, PULL OUT 7672 05:14:46,500 --> 05:14:48,169 JUST DO RNA SEQ AND PULL OUT 7673 05:14:48,236 --> 05:14:49,403 FRAGMENTS OF RNA TO COME FROM 7674 05:14:49,470 --> 05:14:52,807 ANY OF THESE, JUST FROM A FRAG 7675 05:14:52,873 --> 05:14:53,941 FRAGMENT OF RNA, YOU CAN TELL 7676 05:14:54,008 --> 05:14:55,109 EXACTLY WHAT THE CODING CAPACITY 7677 05:14:55,176 --> 05:14:56,177 OF THAT PROVIRUS IS. 7678 05:14:56,244 --> 05:14:57,612 IT'S A VERY POWER TESTIMONY TOOL 7679 05:14:57,678 --> 05:15:02,350 POWERFUL TOOL TO USETO STUDY EXN 7680 05:15:02,416 --> 05:15:03,117 TUMORS AND SO ON. 7681 05:15:03,184 --> 05:15:05,786 SO THE PROVIRUS IN PARTICULAR 7682 05:15:05,853 --> 05:15:08,956 MARKED BY THE BLUE CIRCLE, I HAD 7683 05:15:09,023 --> 05:15:11,259 TO GET A BIT OF NOMENCLATURE, 7684 05:15:11,325 --> 05:15:12,360 I'LL SHOW YOU MORE ABOUT THIS IN 7685 05:15:12,426 --> 05:15:13,527 A MINUTE, YOU CAN SUBDIVIDE 7686 05:15:13,594 --> 05:15:18,366 THESE INTO THREE GROUPS, 7687 05:15:18,432 --> 05:15:28,109 TREE IS THAT THESE ARE 7688 05:15:28,175 --> 05:15:29,543 INTEGRATED INTO -- THESE 7689 05:15:29,610 --> 05:15:31,178 APPEARED IN THE TREE AT A TIME 7690 05:15:31,245 -->
