E Fungi (such as Blastomyces, Coccidioides, and Histoplasma).

45. The future value of gene probes will depend in part on

A. The development of ways to minimize false-positive reactions due to contamination

B. Methods of increasing the sensitivity of tests

`

46. With respect to interpreting BLAST search results, when you do a BLAST search BLAST will come back with a result, that includes

A. The reference of the search program

B. The number of letters in your sequence C. The number of letters in the database D. A graphic representation of the sequence matches E. A list of matches sorted with the best matching sequences shown first F. All of the above

G. A, C & E only

47. In interpreting BLAST results select the answer below that is false.

A. If BLAST returns an E-value that is very small or close to zero, then you probably have a meaningful match that is not due to random chance. B. Since each match therefore contains 2 bits of information (and only 1 is correct out of 4 possibles), then the higher the score, the better is the match.

C. To interpret the matches, you therefore need to pay attention to whether the E-value is reasonably small

D. Two or more sequences may match extremely well but appear to belong to completely different species. E. None of the above
