What is the recognition sequence in restriction enzymes?

Options

  1. AA specific sequence of base pairs recognised by restriction enzymes
  2. BA type of bacteria
  3. CThe first restriction endonuclease
  4. DA methylation enzyme

Correct answer

A. A specific sequence of base pairs recognised by restriction enzymes

Step-by-step solution

: The first restriction endonuclease–Hind II, whose functioning depended on a specific DNA nucleotide sequence was isolated and characterized five years later. It was found that Hind II always cut DNA molecules at a particular point by recognizing a specific sequence of six base pairs . This specific base sequence is known as the recognition sequence for Hind II. Besides Hind II, today we know more than 900 restriction enzymes that have been isolated from over 230 strains of bacteria each of which recognize differe
