Hi I hope you're doing fine.

I need help with these questions please!

 

thank you!

**Question:**

The E value should be as high as possible.

- ○ True
- ○ False

**Explanation:**

In the context of bioinformatics, particularly when using tools like BLAST (Basic Local Alignment Search Tool), the E value (expectation value) represents the number of hits one can expect to see by chance when searching a database of a particular size. It helps assess the significance of the match. A lower E value indicates a more significant match, so the statement should be marked as "False."

The image contains a multiple-choice question regarding the E value from a BLAST search. The options are:

- The probability of finding the match by chance.
- The evolutionary distance between two sequences.
- The equilibrium frequency of codons in the sequence.
- The estimated number of amino acids in the sequence.

Note: A BLAST (Basic Local Alignment Search Tool) search is a method used in bioinformatics to find regions of similarity between biological sequences.
