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

#SCPH05 I 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.

Following are the list of some of the molecular “danger signals” (column I) and its characteristics (column II)                                                                                         

 Column I                                                                                   Column II

 a) MAMPs                               i) produce from the pathogen molecules support their ability to successfully colonize their host and gain nutritional benefits

b) DAMPs                               ii) A plant response to insect herbivores involve both a wound response and the recognition of certain compounds abundant in the insect’s saliva or regurgitant

c) Effectors                             iii) are conserved among a specific class of microorganisms such as chitin for fungi, flagella for bacteria

d) Elicitor                                iv) molecules secrete from the damaging plant by herbivory such as Prosystemin

Which of the following is the correct match between the signals and their respective mechanism?
