- In your earlier research for this case study, you have discovered that nucleotides 1591-1593 (in the cDNA sequence, not CDS) are deleted in many CF patients causing a ΔPhe508 mutation in the CFTR protein. What are these three nucleotides in the CFTR cDNA sequence? Hint: you can copy the cDNA sequence from NCBI (with numbers) into a word processing program (e.g. Microsoft Word) to study the sequence or use a free DNA software program available by searching the internet.Several common antibiotics affect some strains of bacteria's ability to carry out transcription and/or translation. For example: Rifamycin inhibits prokaryotic RNA polymerase Chloramphenicol blocks the transfer of the peptide from the P to A site. a) For each of these drugs, identify at what point it could affect the process of DNA->RNA->protein. Be as specific as possible. b) Why do you think these drugs kill bacteria but spare animal cells? (Hint: remember bacteria are prokaryotes)You are employed in a gene therapy laboratory to test the effectiveness of a vector for correcting the DF508 –CFTR mutation.

- As part of a project investigating potential new drug targets in the fight against malaria, you are seeking to clone the gene for a protein from the malaria parasite Plasmodium falciparum. You wish to express this protein in BL21 (DE3) cells, a standard laboratory strain of Escherichia coli. After purification of your protein, you run an SDS-PAGE gel and notice that the major band has lower molecular weight than expected, so you fear you are getting a truncated version.
