Identify the wrong statement with regard to Restriction Enzymes.
1 They cut the strand of DNA at palindromic sites.
2 They are useful in genetic engineering.
3 Sticky ends can be joined by using DNA ligases.
4 Each restriction enzyme functions by inspection of the DNA sequence.
Explanation:
Sticky ends can be joined by using DNA ligases. The following statement is with regards to ligase and not endonuclease.

BIOXII11:BIOTECHNOLOGY PRINCIPLES AND PROCESSES
347602
EcoRI cleaves the DNA strands to produce:
1 Blunt ends
2 Sticky ends
3 Satellite ends
4 Ori replication end
Explanation:
EcoRI make cut in the two DNA strands at the different position that are staggered by two or four nucleotides leading to formation of short single-stranded overhangs at each end, thus called sticky or cohesive end. They are called so as the base pairing between them can stick the DNA molecule back together again.
