BIOS 390 WEEK 6: LAB: isolate Plasmid DNABIOS 390 BIOS . BIOS 390 WEEK 6: LAB: isolate Plasmid DNA Once a plasmid has been introduced into competent bacterial cells and the cells have grown into colonies on a medium selective for cells containing the plasmid, the next step is to perform a miniprep of the plasmid DNA in preparation for DNA sequencing. The three steps are: 1) growing cells in liquid culture; 2) purifying the plasmid DNA from the culture; and 3) performing a restriction diges...

BIOS 390 WEEK 5: LAB: transcription in prokaryotes Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is called a transcription bubble. Transcription uses one of the two exposed DNA strands as a template; this strand is called the template strand. The RNA product is complementary to the ...
