- Pick a plasmid . What was its approximate transformation? Express it in # colonies per microgram of DNA transformed. Assume the original DNA was about .001 ug/ul . Count how many colonies you got on one plate (or estimate that number) and figure out how much of the total solution you plated on that plate. Multiply by all the plates, if you plated all of it. OR, if you only plated some of it, figure out how many colonies you would have gotten had you plated all of it. Divide by the number of ug used.arrow_forwardStrictly no plagiarism.arrow_forwardgene. If the JM109 strain is transformed by the PBKSK plasmid, the strain will produce the B-galactosidase (from the lac gene) and will hydrolyze X-gal to produce the blue compound.

- This is DWA. You hope to clone an extinct animal species by taking the easy route - using museum bones or tissues. You extract the DNA and use PCR to amplify, then sequence all segments of the genome You are unsuccessful. Later you discover that the museum specimens have been treated with formaldehyde, which forms covalent bonds in DNA, where once there existed H-bonds. What step in your PCR reaction would be inhibited? g -S Knowing this, if a human was exposed to formaldehyde, what enzyme(s) of DNA replication in vivo would be prevented from doing their job?arrow_forwardExplain well.arrow_forwardIn DNA extracting.

- Primer designing: A single-stranded DNA sequence (963 nucleotides) that codes for a hypothetical protein are shown below (lower case shaded blue). 1. Design a pair of forward and reverse primers (~18 nucleotides long each) with EcoRI and BamHI added at 5' and 3' ends, respectively, for the amplification and cloning of this a plasmid with the same restriction sites. gene into GTATCGATAAGCTTGATATCGAATTCatggctaaaggcggagct cccgggttca aagtcgcaat acttggcgct gccggtggcattggccagccccttgcgatgttgatgaagatgaatcctctggtttctgttctacatctatatgatgtagtcaatgcccctggtgtcaccgctgatatta gccacatggacacgggtgctgtggtgcgtggattcttggggcagcagcagctggaggctgcgcttactggcatggatcttattatagtccctgcaggtgttcctcg aaaaccaggaatgacgagggatgatctgttcaaaataaacgcaggaattgtcaagactctgtgtgaagggattgcaaagtgttgtccaagagccattgtcaacctg atcagtaatcctgtgaactccaccgtgcccatcgcagctgaagttttcaagaaggctggaacttatgatccaaagcgacttctgggagttacaatgctcgacgtagt cagagccaatacctttgtggcagaagtattgggtcttgatcctcgggatgttgatgttccagttgttggcggtcatgetggtgtaaccatttgccccttctatctcagg…arrow_forwardBioinformatics.
