Correlation between tubulin mRNA stability and poly(A) length over the cell cycle of Physarum polycephalum

During the cell cycle of the Physarum polycephalum plasmodium, levels of α-tubulin mRNA rise exponentially in G 2 phase, reach a peak at metaphase 40-fold above basal levels, and then fall exponentially to basal levels after mitosis. We show that post-mitotic α-tubulin mRNA carries poly(A) tracts of...
