I struggled with this and thought about Jake's wind sounds etc. but I went for a morse code approach.... We talk about DNA Code... so it seemed appropriate.. I scrambed this with some distorted poor radio reception and tapes rewinding.... I was quite pleased with the result but it is probably a bit 'intense' for the interviews which follow!
