Which of the following sentences best descrives the difference between a global alignment and a local alignment between two sequences?

a) global alignment is usually used for dna, while local alignment is usually used for protein sequences.
b) global alignmnet has gaps, while local alignments does not have gaps
c) global alignment finds the global max, while the local alignment finds the local max.
d) global alignment aligns the whole sequence, while local alignment finds the best sub-sequence that aligns

The correct answer is option D.

Explanation:

A sequence or the arrangement of the DNA, protein, or RNA sequence to recognize the part that shows similarities due to the evolutionary, structural, or functional relation in between sequences.

There are two types of alignment techniques in bioinformatics one global and other local. Local alignment is more helpful as it is better in identifying dissimilar sequences that might contain regions of the similarities. Global alignment techniques align the whole sequence whereas local alignment aligns subsequences.

Thus, the correct answer is - option D.
