Speed-taboodunit is a mashup of speed-dating, taboo, and whodunit; the idea is that each person writes on a piece of paper something unusual about themselves, underlining the key words, then these pieces of paper are randomly redistributed. Everyone organizes in a speed-dating format, with two lines of people, and you have a minute to talk to them and try to find out if they're the person described on their piece of paper-- with the catch that they can't use any of the underlined words. People who successfully find their person leave the group, but otherwise after the minute everyone moves down the line. As for why we came up with this specific icebreaker, we wanted to hit two key requirements of icebreakers: they have to be fun, and they have to make specific accommodations for being shy or quiet. Because each person has the specific objective of finding their person, this helps them overcome the shyness, and as for the fun, everyone loves taboo!

A lot of iGEM teams we've looked at don't have much beyond the biology, so we really try hard to do interdisciplinary projects, as they provide a great opportunity for learning to work with different kinds of people.

We transformed parts containing carotenoid pathway genes crtE, crtI, crtB, and crtY (BBa_K523022, BBa_K539119, BBa_K145001), as well as the T7 promoter (both in pIVEX2.3d as well as BBa_I712074), the T7 polymerase gene (BBa_K145001), and the transformation efficiency kit part (BBa_J04450).

From the plasmid pUCATPH (pAh13G), we amplified the trpC promoter (PtrpC, a constitutive fungal promoter) and the trpC terminator (TtrpC). From pNG (pAg13H), we amplified nptII, the geneticin (a plant/fungal antibiotic) resistance gene.

We miniprepped the crtEIB (BBa_K523022), crtY (BBa_K539119), and T7 (BBa_I712074) biobricks. The gels confirmed our PCRs for PtrpC, TtrpC, and nptII, which we then digested to insert into pSB1C3.

PtrpC, TtrpC, and nptII were column-purified, digested pSB1C3 backbone was gel-purified and dephosphorylated, and each was ligated into the pSB1C3 backbone.

We transformed TtrpC (pC13Q), PtrpC (pC13P), and nptII (pCg13R) constructs into DH5α via electroporation.

We used Q5 PCRs with the standard biobrick primers VF2 and VR to attempt to confirm the presence of TtrpC (pC13Q), PtrpC (pC13P), and nptII (pCg13R).

Minipreps of TtrpC (pC13Q), PtrpC (pC13P), and nptII (pCg13R) were performed with an EZNA kit, and afterwards we quantified with a nanodrop.

The Q5 PCRs of TtrpC (pC13Q), PtrpC (pC13P), and nptII (pCg13R) showed bands of the correct size, so sequencing with VF2 and VR was submitted to make sure nothing strange had happened.

pC13B (crtY) was digested with XbaI and PstI, and pAK13D (T7 promoter) with SpeI and PstI (standard RFC 10 cloning). However, the gel showed only one band for each (what one would expect for pAK13D, but pC13B should have had two bands).

pC13B (crtY) was digested with XbaI and PstI, and pAK13D (T7 promoter) with SpeI and PstI (standard RFC 10 cloning). The gel this time had two bands at the correct locations for pC13B, so we're hoping it's a success this time. We also started overnight LB cultures of pAb13T (pBARGPE1).

If successful, the ligation will form pAK13AD. pC13K (crtI, BBa_K118003) and pC13M (crtB, BBa_K118002) were digested with XbaI and PstI for insertion into pAK13D, and separated on a gel. pAb13T (pBARGPE1) was miniprepped and quantified by nanodrop.

pC13K (crtI, BBa_K118003) and pC13M (crtB, BBa_K118002) were digested with XbaI and PstI, pAK13D with SpeI and PstI, pC13Q (TtrpC) with EcoRI and XbaI, and pCg13R (nptII) with EcoRI and SpeI, and all were separated on a gel; crtI looked faint, and pAK13D was smeared, but all fragments were cut out for purification tomorrow.
