14 Questions
What does MSA refer to?
The process or result of aligning three or more biological sequences
What can be inferred from the resulting MSA?
Sequence homology and shared evolutionary origins
What do hyphens in the alignment represent?
Insertion or deletion mutations (indels or gaps)
What is the assumed relationship among the input set of query sequences in MSA?
They share a linkage and are descended from a common ancestor
What can be assessed using multiple sequence alignment?
Sequence conservation of protein domains, tertiary and secondary structures
What is the primary purpose of multiple sequence alignment?
To identify conserved regions and functional domains
Why is it challenging to perform multiple sequence alignment on highly divergent sequences?
Due to the difficulty in identifying homologous regions
What is the role of gap penalties in multiple sequence alignment?
To discourage excessive introduction of gaps in the alignment
What is the main goal of multiple sequence alignment (MSA)?
To identify conserved regions and evolutionary relationships among sequences
Why is it challenging to perform multiple sequence alignment on highly divergent sequences?
Because highly divergent sequences may have limited or no homologous positions
What do gaps in a multiple sequence alignment represent?
Variability between sequences
What is multiple sequence alignment?
A method to align three or more biological sequences
Why is multiple sequence alignment important?
To identify conserved regions and functional motifs
What is the primary goal of multiple sequence alignment?
To identify evolutionary relationships and conserved regions
