What is the primary purpose of using a scoring matrix in sequence alignment?
To determine the evolutionary distance between sequences
To assign penalties for gaps and mismatches
To visualize the alignment
To calculate the overall alignment score
In the context of sequence alignment, what does the term 'gap penalty' refer to?
The score given for matching identical residues
The score deducted for introducing a gap in the alignment
The score for mismatched residues
The score for aligning sequences of different lengths
Which of the following statements is true regarding local sequence alignment?
It aligns entire sequences from start to finish.
It is useful for finding conserved regions within sequences.
It always produces a longer alignment than global alignment.
It can be performed using the Smith-Waterman algorithm.
What is the significance of the E-value in sequence alignment results?
It indicates the number of alignments with scores equivalent to or better than the observed score.
It represents the length of the alignment.
It measures the similarity between sequences.
It is used to assess the quality of the alignment.
