Part:BBa_K3893009
Down part of cassette for dsRNA constitutive production 1
Part of Modular Platform for dsRNA production
Lower part of the cassette for constitutive dsRNA production, which is composed of a GFP transcription unit that functions as a dropout, RBS (BBa_B0034), promoter T7 (BBa_I712074) and terminator (BBa_K3893007).
Assembly system
Before constructing the modified plasmids and using them, we took into account the following: ○ Have a Biobrick-compatible backbone, in case you don't have it you could modify it with PCR overhang and add RFC10 prefix and suffix. ○ The following restriction enzymes are used: EcoRI, PstI, SpeI, XbaI, BglII and KpnI. Therefore the dsRNA sequence should not contain these restriction sites. ○ Previously carry out PCR overhang to the dsRNA sequence to add the restriction sites: BglII and KpnI.
Once the above considerations have been met, the following assemblies are performed: 1) We synthesized the up (UP) and down (DP) parts and cloned them into Biobrick-compatible backbones with EcoRI and PstI. 2) Assembly 3A adapted: We digested the UP plasmid with EcoRI - SpeI, the DP plasmid with XbaI - PstI and a Biobrick compatible backbone with EcoRI - PstI. Then we ligated and obtained as product the modified plasmid (dsRNA receptor). 3) We inserted the dsRNA into the plasmid by digesting and ligating both sequences with BglII and KpnI.
