Options

  1. AA-II, B-I, C-III, D-IV
  2. BA-I, B-II, C-IV, D-III
  3. CA-II, B-I, C-IV, D-III
  4. DA-I, B-II, C-III, D-IV

Correct answer

D. A-I, B-II, C-III, D-IV

Step-by-step solution

According to NCERT, exonucleases remove nucleotides from the ends of the DNA, whereas endonucleases make cuts at specific positions within the DNA. EcoRI is a restriction endonuclease that recognises the palindromic sequence GAATTC and cuts the DNA between bases G and A, producing sticky ends. A palindromic sequence in DNA is a sequence of base pairs that reads the same on the two strands when orientation of reading is kept the same. Therefore, the correct matching is A-I, B-II, C-III, D-IV. Answer: A-I, B-II, C-II
