Which of the following statements is/are correct ?  

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. If E > 10, the sequences under consideration are either unrelated or related by extremely distant relationship.
  2. BLAST score decrease higher sequence similarity.
  3. If E is between 0.01 and 1e − 50, the match can be considered a result of homology.
  4. The lower the E-value, the less likely the database match is a result of random chance
