Answer: C. Full step-by-step solution below.
- A5' -CATTAG- 3'
3' -GATAAC- 5' - B5' -GATACC- 3'
3' -CCTAAG- 5' - C5' -GAATTC- 3'
3' -CTTAAG- 5' - D5' -CCAATG- 3'
3' -GAATCC- 5'
Correct answer: C
Solution
(c) A palindromic DNA sequence reads the same in the 5'→3' direction on both complementary strands. GAATTC is a classic palindromic site recognized by EcoRI.More Biotechnology: Principles & Processes PYQs
