Which statement is correct for statistical significance of sequence alignment?

#SCPH01 Biochemistry

Statistically significant sequence alignment will be able to provide evidence of homology between the sequences involved.
Statistical significance provides the proof that observed sequence alignment can occur by random chance or the alignment is indeed statistically.
PRSS is a web-based program that can be used to evaluate the statistical significance of DNA or protein sequence alignment.
