Q. Consider the following statements about multiple sequence alignment (MSA).

1.MSA aligns three or more related sequences.

2.MSA can help identify conserved residues and regions.

3.MSA is useful for phylogenetic analysis.

4.MSA is useful only for DNA sequences, not protein sequences.

Which statements are correct?
