Mutations in <i>rec</i>

<p>The <i>rec</i> gene contains two exons and an intron. Untranslated regions are open and protein-coding regions are filled, with the MCM core indicated by gray fill. Amino acid numbers are shown below the model, and the positions of the four mutations sequenced are shown above. The locations of the Walker A and B boxes are shown as black bars and are labeled below the model. Only the position of the intron is indicated. The full intron is 5.5 kilobases and contains another predicted gene <i>(CG4576),</i> transcribed in the opposite direction.
