Options

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

Correct answer

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

Step-by-step solution

Restriction endonucleases function by inspecting the length of a DNA sequence to find their specific recognition site (A-III). DNA ligase is an enzyme that facilitates the joining of DNA fragments by catalyzing the formation of phosphodiester bonds, thus joining the sugar-phosphate backbones (B-I). A palindromic sequence in DNA is a sequence of base pairs that reads the same on the two strands when the orientation of reading is kept the same, such as in the 5' 3' direction (C-II). Sticky ends are single-stranded ov
