Fint the incorrect statement about Multiple Sequence alignment (MSA).

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. Sum of pair and Shannon’s entropy score are calculated to estimate optimal alignment in MSA.
  2. Shannon’s entropy in a MSA alignment < 1 are consider as a conserved region.
  3. Iterative alignment in comparison to Progressive alignment gives better and faster results.
  4. Example of Progressive alignment is Clustal and MUSCLE is an example of Iterative method.
