The specific palindromic sequence which is recognized by EcoRl is

Options

  1. A5 ' - GGAACC - 3 ' 3 ' - CCTTGG - 5 '
  2. B5 ' - CTTAAG - 3 ' 3 ' - GAATTC - 5 '
  3. C5 ' - GGATCC - 3 ' 3 ' - CCTAGG - 5 '
  4. D5 ' - GAATTC - 3 ' 3 ' - CTTAAG - 5 '

Correct answer

D. 5 ' - GAATTC - 3 ' 3 ' - CTTAAG - 5 '

Step-by-step solution

Palindrome 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. These sequences may range from 4-8 nucleotides in length. For example, the restriction site for EcoRI is between G and A residues in the palindromic sequence given below.                     ↓ 5 ' -   G A A T T C   - 3 ' 3 ' -   C T T A A G   - 5 '             &#
