Figure 4. Stem-loop structures identified within the 232-bp pRN1 putative origin of replication.

Figure 4

(A) The secondary structure of 232-bp putative origin of replication determined using DNA mFold, revealed the presence of 100-bp (4734 - 4833) and 19-bp (4693 - 4711) stem-loop (SL) structures at 70°C. (B) DNA sequence of the 232-bp putative origin of replication showing the 100-bp SL (single underline) and 19-bp SL (double underline) in pRN1 origin. Deletions made in pRSP1a (between ∆), pRSP1b (between∇), pRSP1c (between ▼) and pRSP1d (between ▲) are highlighted by the triangles, while the deletion in pRSP1e is shaded. The ‘GTG’ motif (box) and the loop of the 100-bp SL (red) are also highlighted.
