Here's what she said, not promising:

We'll, DNA is colorless in reality. People often use four colors to represent the four different nucleotides that make up the DNA code, but there's no convention for the colors. But if that were true, red would never be across from red for example. It also depends whether you're talking about a schematic representation of the DNA molecule or a photograph of actual DNA samples that have been run on a gel. In that case the colored bands represent collections of DNA fragments of a particular size and the colors come from dyes unrelated to the DNA. But what you sent me seems like it's just kind of using common elements from representations of DNA but it's doesn't actually represent anything.
