Question

1. The confirmed diagnosis that Baby T had Bartter syndrome was based on the use of ____, which sequenced only the protein coding regions of the genome.

     a. whole genome sequencing    b. whole exome sequencing    c. whole intron sequencing

     d. SNP analysis    e. whole proteome analysis

2. Approximately what percentage of the human genome encodes proteins?

a. 1    b. 3    c. 5    d. 15    e. 50

3. Positional cloning is used to link the inheritance of a disease in a pedigree to the inheritance of _____.

     a. other diseases or conditions   b. a specific blood type   c. other genes whose loci were known

     d. marker sequences produced by restriction enzymes   e. X-linked genes

4. One method of reducing the amount of data needed to examine while looking at DNA sequences, is to only

    a. sequence the disease causing genes   b. look at the exome    c. use non-coding sequences

    d. sequence the template strand    e. use proteins to show what DNA is important

5. If gene “A” has a crossover frequency with gene “B” of 16% and gene “B” has a crossover frequency with gene “C” of 8% and gene “A” has a crossover frequency with Gene “C” of 8% what is the order of these genes on the chromosome?

    a. A-B-C      b. A-C-B     c. B-A-C    d. Insufficient Information.

Explanation / Answer

1-b(exome sequencing is used to identify genetic variation that alter protein sequence.this variation may cause polygenetic diseases.)

2-a(only 1.5%of the genome code for proteins)

3 d

4 d
