Biology 3210 Laboratory Lab Report 1 Detection of genetically modified maize in from commonly available corn food product Introduction A genetically modified organism (GMO) is an organism which has had its genome modified by the addition of genetic material from another species (Steynen‚ 2012). There are many debates surrounding genetically modified organisms on both personal levels‚ global levels and anywhere in between. There are issues on whether food produced with GMOs is safe‚ if it

genetics laboratory for p53 mutation analysis. DNA isolated from the tumor cells was screened for sequence alterations due to difference in the nucleotide sequence caused by mutations in the exon 4 to 9 of p53 gene. The results of polyacrylamide gel electrophoresis and subsequent direct sequencing for exon 5 are shown below: What information is gained from PAGE results? What additional information is gained from sequencing in regards to the patient condition? References Lewis‚ R. (2012). Human Genetics:

The recombinant protein will be isolated‚ purified and characterized by SDS-PAGE and Western blot. Several chromatographic techniques including gel filtration and affinity chromatography will also be employed for the purification of the recombinant human PDGF-B.

1. The overall goal of this lab was to carry out experiments that clearly demonstrate the different ways DNA genetic information‚ specifically transduction and conjugation. The first half of this experiment focused on exploring the mechanisms of transduction. This was done by creating a spot titer plate for phage carrying kanamycin resistance and E. coli. E. coli was then proven to have gained kanamycin resistance throughout transduction as demonstrated by its ability to grow on a medium containing

DNA TECHNOLOGY How is DNA technology used in law enforcement? There are many different ways it is used‚ but it is mostly used to solve crimes. Much like deaths‚ rapes‚ or even big robberies. DNA is a way to identify a person by: blood‚ hair‚ skin‚ saliva etc... That is why when people are trying to discover a murderer they are very careful when they are collecting evidence.That is why when something occurs‚ everything is blocked off‚ and only investigators could pass into the area

Cindy is an expectant mother who is eight weeks pregnant with her first child. She is having a genetic test because there is a history of learning disabilities and mental impairment in her family. Based on her family history‚ there is a possibility that she is a carrier for Fragile X‚ a genetic disorder that occurs when a person’s X chromosome(s) contains greater than 200 repeats of the CGG base pair sequence. Symptoms in infants include a delay in crawling‚ walking‚ or twisting‚ frequent hand clapping

regard to LDH purity was Size Exclusion (0 fold). However‚ those results would have been better if we did not have a problem with the column‚ as already mentioned above. We were able to visualize purity by analyzing the SDS-PAGE gel (Figure 8). We can clearly see in the gel‚ that the Clarified Homogenate is more pure than the 65% cut LDH. We should have been able to visualize that the best purification step was Affinity Chromatography‚ but during the experiment‚ instead of adding the 5x sample buffer
