Question 1 (5 points) di What can you conclude from the following record parameters obtained from a Blastn search? Coverage: 65%; E value: 6e-168; Ident: 90% Choose all correct conclusions. A) The probability of the query sequence being a good match is 90% B) In 65% of cases a 90% match was found with the query sequence. C) The query sequence was 90% identical to 65% of the sequence found. D) 90% of the sequence found was 65% identical to the query sequence. E) The likelihood of this match to have occurred by chance is equal to (6e-168) F) It is more probable that the match found is a true match as compared to an alignment made with a sequence with an E value of 2e-50 and a coverage of 100% G) 65% of the query sequence was 90% identical to the sequence found.
