We used Gel Electrophoresis to test whether we have the DNA we wanted. As we already know, the ''ara'' gene is about 300bps. We used hundred bp DNA ladder as a guidance for our bands. The two bands produced were from two separate ''ara'' cultures and they indeed show the bands in the same region, i.e. 300bps.

Chromosomal prep

Results

We used Gel Electrophoresis to test whether we have the DNA we wanted. As we already know, the ara gene is about 300bps. We used hundred bp DNA ladder as a guidance for our bands. The two bands produced were from two separate ara cultures and they indeed show the bands in the same region, i.e. 300bps.

Conclusion

The aim of this whole experiment was to extract genomic DNA from B. subtilis strain ATCC 6633. In order to test whether we had extracted the DNA, we first used PCR to amplify and then used Gel Electrophoresis to compare the bands of ara genes to the hundred bps ladder.It worked!

LacI BioBrick Construction

Aims

  • To use PCR to extract lacI (promoter, ribosome-binding site (RBS) & coding sequence (CDS)) from plasmid pMutin4 and ligate into vector pSB1AT3 in front of red fluorescent protein (RFP).

Materials

  • Digested plasmids pMutin4 and pSB1AT3
  • PCR product
  • Restriction enzymes EcoR1 and Spe1

Protocol

  • The digests and PCR product are run on an agarose gel
  • pSB1AT3 is excised from the gel
  • lacI PCR product is purified.
  • Purified lacI is restriction digested with EcoR1 and Spe1.

Results

  • Bands were seen at the correct size for pMutin4 and pSB1AT3 and the amplified PCR product.

Conclusion

  • The digested plasmids and the PCR product were run on an agarose gel in order to determine what was in these samples. The samples should have run at . The samples did in fact run in this manner, and so it can be said with confidence that our protocols have worked as they should.

Inference

  • The purified PCR product is cut to give it sticky ends complementary to the digested pSB1AT3. pSB1AT3 is excised from the gel ready for gel extraction.
