         <ul>
           <li>
-            A Quick change mutagenesis of pMK1 was performed using a longer elongation time and a temperature gradient to find the perfect annealing temperature.
+            we ordered new primers which should bind better
           </li>
-        </ul>
-        Primer:
-        <ul>
           <li>
-            FW_pMK1_RE4_G->C
+            we also ordered primes to remove the second BsmBI-Binding sequence behind the poly-A tale
           </li>
           <li>
-            RW_pMK1_RE4_G->C
+            we would also try a new method to generate repeats called the rolling circle method where circular DNA containing only 4 repeats of resilin is generated. Than a phi29 polymerase will circulate around this circular DNA generating more repeats.
