The use of low-complexity masking in the BLAST procedure means that it may have higher specificity than FASTA because potential false positives are reduced. Select one: a. Can't say b. True c. False d. True in some cases only

It is important to mask repeats before gene annotation, as repeats will cause non-specific gene hits True False

Whenever possible opt for ‘source-of-truth’ designated data.Select one:a. Trueb. False

Context: Changing which of the following BLAST parameters would tend to yield fewer search results? (a) turning off the low‐complexity filter; (b) changing the expect value from 1 to 10; (c) raising the threshold value; or (d) changing the scoring matrix from PAM30 to PAM70 Answer question

n IN operater is used to specify the only value in a column.Select one:a.TRUEb.FALSE

Which output from a BLAST search provides an estimate of the number of false positives from a BLAST search? (a) E value; (b) bit score; (c) percent identity; or (d) percent positives.
