Question

ECORI cleaves the DNA strands to produce

• A. Blunt ends
• B. Sticky ends
• C. Satellite ends
• D. Ori replication end

Answer 1

The correct option is B Sticky ends

• Sticky ends are formed when the restriction enzymes cut the DNA molecule at such a position that it leaves an overhanging stretch of the nitrogenous base which can pair with the complementary base pairs.
• EcoRI cut through the DNA strands at nucleotides that overhangs at the end.
• This overhanging nucleotide strand is called a sticky end because it can easily bond with complementary DNA fragments. So, the correct answer is option B.
