DNA project 'to make UK world genetic research leader' says the headline.

What looks like a hand-drawn Figure 1. in this Journal of Organic Chemistry article. I can't spot any particular reason why it might be hand-drawn (as in, something clever which relates to the article itself). Any ideas? Also, that left-pointing retrosynthesis arrow seems inelegant to me. What's wrong with a standard reaction arrow?
