This is a LaTeX package for drawing genetic construct pictograms using TikZ. Under development, there are no reusable macros at the moment.

We provide a TikZ library called dna that installs one core macro, \dnaplot.

\usetikzlibrary{dna}
\begin{tikzpicture}
  \node (dox) at (0,1) {dox};
  \dnaplot []
    features
    { [name=segment 1] {
        promoter        [name=p1],
        coding sequence [name=gA],
        terminator
      },
      [anchor=north west, right=1cm of segment 1.base east] {
        promoter        [name=p2],
        coding sequence [name=gB],
        terminator
      }
    }
    regulation { (dox) -| {gB -| p1, gA -| p2} };
\end{tikzpicture}

Compare this image with this gallery entry from dnaplotlib. The image above was drawn entirely in TikZ, the source is in example.tex.
