Which of the following is incorrect regarding the progressive alignment method?

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. It speeds up the alignment of multiple sequences through a multistep process.
  2. It first conducts pair wise alignments for each possible pair of sequences using the Needleman–Wunsch global alignment method and records these similarity scores from the pair wise comparisons
  3. The scores can either be percent identity or similarity scores based on a particular substitution matrix.
  4. Its drawback is it slows down the alignment of multiple sequences through a single step process.
