This is the iteration plan for the Construction iteration(s). See [http://www.upedu.org/upedu/process/artifact/ar_itpln.htm the UPEDU artifact description] for information on what this is and what it contains (including a template).

Milestone

These are the major [http://www.upedu.org/upedu/process/itrwkfls/ms_ioc.htm milestone objectives] for the Construction phase:

  • TODO Our wonderful buoyant, metal filtering bacteria should be alive and kicking!
  • TODO (?) The lab/plan cloning strategy should be fully worked out at the end of the phase to reflect our final decisions on which parts/protocols/procedures/? to use. (I think this roughly corresponds to the Implementation Model in UPEDU. --Jaspervdg 11:09, 23 June 2009 (UTC))
  • TODO The Iteration plan for the transition phase completed and reviewed.
  • TODO (?) Design Model (and all constituent artifacts) updated with new design elements identified during the completion of all requirements. (I think this can roughly be seen as fleshing out all the device designs and parts, or in other words: making sure The Project is up-to-date. --Jaspervdg 11:09, 23 June 2009 (UTC))

Resources

Note that we're opting to do this for the entire phase instead of each iteration as in UPEDU as this seems more natural (our needs change little over the course of one phase). --Jaspervdg 11:01, 23 June 2009 (UTC)
[Resources needed for the phase — material, human, financial, and so on.]

      3. Add the terminator to the construct
      4. If needed add promoter (constitutive promoter --> ) to do initial phenotype testing.
    • Metal transporters (Jolanda, SJ)
      1. Transform E. coli with construct (HmtA first, get GlpF either by ordering or by genome PCR. Then order primers + pre/suffix and RBS in prefix).
      2. Test insert length.
      3. Silence restrictionsites in HtmA by PCR (2x PstI) and add BioBrick pre/suffix.
      4. Clone the terminator in to the construct.

        2. Constitutive are: High expected expression yield, and Low expected expression yield, Lac promoter with mutated operator . For these promoter sequences are too small, oligo's have to be ordered + BBa pre/suffix !!without RBS!!
        3. Metal sentitive are possibly copA (order oligo's) and ??
          1. Clone in such a way that they are nicely -10 / -30 in front of the start codon.
