Fig. 2. Photograph of polyacrylamide gel (10% acrylamide) showing the relative
abundance of myosin A (204 nucleotides, nt) and myosin B (189 nt) mRNAs
following RT-PCR of RNA from muscle fibres of the transverse muscle mass of
the arm (middle lane) and the tentacle (right lane). The 1 kb ladder (left
lane) confirms the size of the products.
