What does this statement mean
Restriction enzymes cut the strand of dna a little away from the center of the palindrome sitesbut between the same 2 bases on the opposite strands
.this leaves single stranded portion at the ends

Dear student, 

Restriction enzymes cut the strand of DNA a little away from the centre of the palindrome sites but between the same two bases on the opposite strands. So that a single stranded unpaired bases at cut ends will be left to form a hydrogen bonds with their complimentary cut counter parts. These ends are known as sticky ends that  facilitate the action of enzyme DNA ligase.

Regards
