Identify the wrong statement with regard to Restriction Enzymes.

1

Each restriction enzyme functions by inspecting the length of a DNA sequence.

2

They cut the strand of DNA at palindromic sites.

3

They are useful in genetic engineering.

4

Sticky ends can be joined by using DNA ligases.

Step-by-Step Solution

Restriction endonucleases make cuts at specific positions within the DNA. They function by inspecting the length of a DNA sequence. Restriction endonuclease bind to the DNA and cut the two strands of double helix at specific points in their sugar-phosphate backbones. They are used in genetic engineering to form recombinant molecules of DNA. DNA ligases join the DNA fragments.
