Week 10

Monday 3rd September 2007

  1. Christine's plates from 31/08/07 all grew except for 1B. Overnights were set up from 7 colonies on each of the plates on Sunday, labelled 1A1→1H7, 49 in total as there were none from plate 1B. Christine, Maia and Maija miniprpped them and digested them as follows:
    This table is incorrect, see 04/09/07.
    PCR tube Colony DNA is taken from Insert Enzyme Expected sizes Result
    1A D (*a→d*) EcoRI 3455bp, 18bp, 3654bp Negative
    1B D (*a→d*) PstI 274bp, 6553bp Negative
    1C S (*d→g*) EcoRI 7046bp, 18bp, 284bp Negative
    1D S (*d→g*) PstI 1155bp, 2511bp, 3682bp Negative
    1E S (*d→g*) PstI 1962bp, 1704bp, 3682bp Negative
    1F Q (*d→g*) EcoRI 7046bp, 18bp, 284bp Negative
    1G Q (*d→g*) PstI 1155bp, 2511bp, 3682bp Negative
    1H Q (*d→g*) PstI 1962bp, 1704bp, 3682bp Negative

    1. Christine realised that the site directed mutagenesis she had attempted on Thursday 30/08/07 was wrong. S and Q were meant to be tested for (*a→d*), and D was meant to be tested for (*d→g*) but S and Q were tested for (*d→g*), and D was tested for (*a→d*). This means the digests from 03/09/07 were also incorrect. However, all is not lost because the sequencing results for S and D came back today and they show that both S and D contain (*d→g*).
