Answer #1

Cytochrome C oxidase 1 (COX1) is a DNA barcode sequence present in the mitochondrial DNA. It has conserved flanking sequences from which primers can be designed. The barcode sequence has high inter-species variability and low variability within a species. This makes it possible to identify the species based on the barcode sequence and using a reference library.

    You need to amplify a specific DNA sequence from a dried drop of blood at a crime scene. A forensic hematologist informs you that there are approximately 1000 white blood cells and 5000 red blood cells in this dried sample. She also confirms that the sample is human blood. The DNA sequence you choose to amplify occurs once per haploid genome. If you perform 30 cycles of amplification in a thermal cycler using Taq polymerase, how many copies of the...

    Bacteria use DNA methylation as a method to label their DNA, so they can identify foreign DNA and degrade it using restriction endonucleases. This DNA methylation is different than that of eukaryotic organisms, in that it adds a methyl group to adenine. This makes the bacterial DNA methylation system a potential antibiotic target. Question 1: (3 marks) Based on what we learned about enzyme activity and regulation, explain what you would expect for the following enzymes: How would this differ...

    13. A newly developed DNA diagnostic test can sequence DNA obtained from a mother's blood sample to test whether a fetus is carrying trisomy 21 (which causes Down syndrome). In mothers over 45 the chance of having a child with Down syndrome is 5%. If the test accurately detects trisomy 21 95% of the time and has false positive rate of only 2% (i.e. the fetus is incorrectly diagnosed as having trisomy 21) what is the probability that a child...
