- One of the patient's two alleles has a deletion mutation in which a single T has been deleted.
The Chromatogram has the sequence GATC A/T A/C C/C T/C T/A A/G
The original sequence of the gene is GATCTACCTAG. If one allele has the second 'T' deleted, the allele sequence will be GATCACCTAG (GATC A/T A/C C/C T/C T/A A/G), which leaves the sequence of the second allele as GATCTACCTA.

2. (5 PTS) You are presented with a patient, named Gerry, who has Down syndrome (trisomy 21). You determine that the nondisjunction event occurred in his mother, named Mary, during meiosis I. a. You are interested in the TPTE gene, which is near the centromere of chromosome 21. Virtually no recombination occurs between the centromere and the TPTE gene. Mary has two different alleles of the TPTE gene. Would Gerry's two chromosome 21s from his mother have the same or...

Translocation and deletion 3. You PCR amplify a 500 bp (base pairs) piece of DNA that has diagnostic value in determining whether a patient has a mutation within a specific DNA region. You know that this DNA segment of the "normal" gene does not include an EcoRI restriction site; but the mutated DNA segment of the same gene contains an EcoRI restriction site due to a point mutation at...

1) You have two human liver cells (A and B) and you hypothesize that the insulin receptor gene in Cell A has a mutation in exon 1 and Cell B contains the wild type sequence. You extract genomic DNA from each of the cells. Of the following, what would be the most efficient (quick, precise and relatively cheap) way to test your hypothesis. a. Isolate protein from both cells, purify the insulin receptor, and determine the amino acid content. b. Sequence the...

Not sure how to answer my Immunology questions! Help! 2) You encounter a patient that has been found to have an inability to mount an immune response to bacterial infections other than IgM. Suppose the following are plausible issues: 1) The patient is lacking Macrophages able to present antigens to T Cells (ergo only getting a B-Cell response without T Cell activation) 2) The patient either lacks expression of CD 40 (B Cell) or CD 40L (T Cell) 3) A...
