Click here to pull in the data for this tutorial. The sequences pTypeIIS, CMV, and GFP will be added to a Training project called Training and opened for you.

We will do a Golden Gate assembly using the Assembly Wizard by cloning the CMV promoter followed by GFP into pTypeIIS, with a Kozak sequence between the two inserts.

To access the Assembly Wizard, first open a sequence file. Look to the bottom of your screen and find Assembly Wizard next to Split Workspace. Click Assembly Wizard > Create New Assembly. 

Select Golden Gate and press Start.

Open pTypeIIS and click the Backbone slot. Notice that the BsaI cut sites are already filled in. Press Set Fragment to set the backbone.

Open CMV and click the Insert slot. Select all of CMV’s bases. Press Set Fragment to set the first insert.

Press the plus button at the right of the assembly wizard to add another insert. Open GFP and click the new Insert slot. Select all of GFP’s bases. Press Set Fragment to set the second insert.

Click the Insert (CMV) slot and press Add Spacer After, the last button. Name the spacer “kozak” and set its bases to gccacc. Press Save to set the spacer sequence.

Rename the assembly to “pTypeIIS-CMV-GFP (golden gate)” and press Assemble at the right of the assembly wizard.

Select Training for both the Sequence Folder and Primer Folder. Press Create to complete the assembly.

Notice that the backbone and insert fragments on the assembled sequence are colored. Open the History panel’s Lineage tab to see its lineage.

Open the Assembly tab to see an overview of the assembly, print it, and export the primers.

Replace the 2268th base "T" with "C." This introduces a point mutation in the 4th base of CMV. Notice that the CMV FWD primer automatically updates and the mutation appears in the Assembly tab’s Mismatches Introduced table.

To enable aligning to the assembled sequence or making arbitrary edits on it, open the Assembly tab and press Finalize at the top right.

Next, learn how to clone using Digest and Ligate or Gibson Assembly Wizard.
