Which of the following statements is/are correct about PAM Matrix ?

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology

A PAM unit is defined as 1% amino acid change or one mutation per 100 residues.
The increasing PAM numbers correlate with increasing PAM units and thus evolutionary distances of protein sequences.
PAM250, which corresponds to 20% amino acid identity, represents 250 mutations per 100 residues.
PAM matrices with lower serial numbers are more suitable for aligning more closely related sequences.
