The infographics main message is convey, that the Human Genome (the complete set of nucleic acid sequence for humans encoded as DNA within the 23 chromosome pairs) holds the blueprint to the entire human body.
By looking at a particular part of your body, for instance your heart and associated symptoms, one can look at the genome. Once the
Many diseases or symptoms you experience can be traced back to your genome and the respective Chromosome. From research, there is a good understanding, where in the genome we need to look at, to identify the respective genetic information. Within this chromosome, once drilled down to the DNA, we can identify the sequence of the pairs (depicted as the four letters A G C T).
The sequence is then eventually decoded and being displayed on the "computer screen" for analysis.
The look and feel of the infographic needs to be interest grabbing as well as easy to understand, yet be professional and creative (guess that's as precise as I can be:)
