Chapter 6, Problem 3P

Interpretation Introduction

Interpretation:

The alignment that has a higher score according to identity-based alignment scoring.

Concept introduction:

Identity−based alignment scoring is a method to score the identical alignments present in a sequence. The identical amino acids are added while the gaps in the sequence are subtracted to determine the identical score.

Interpretation Introduction

(b)

Interpretation:

The alignment that has a higher score according to the Blosum -62 substitution method.

Concept introduction:

Blosum-62 is a type of substitution matrix that is used to score the replacement of amino acids. A positive score of substitution matrix indicates that substitution of amino acid occurs more frequently while a negative score is rare for substitutions.
