Identify the wrong statement with regard to Restriction Enzymes.
A
Each restriction enzyme functions by inspecting the length of a DNA sequence.
B
They cut the strand of DNA at palindromic sites.
C
They are useful in genetic engineering.
D
Sticky ends can be joined by using DNA ligases.
Answer
Sticky ends can be joined by using DNA ligases.
Explanation
Solution
Sticky ends contain free or hanging or unpaired nitrogen bases which can pair to complementary bases present on other DNA segment required to create a recombinant DNA. A ligase is required in absence of sticky ends to join together two segments of DNA. So, the correct answer is 'Sticky ends can be joined by using DNA ligases.'
