Definitions:

Restriction Enzymes

Enzymes used in molecular biology to cut DNA at specific sequences, allowing for DNA manipulation.

Single-stranded Tails

Single-stranded tails refer to the unpaired regions of nucleic acids that extend from the main double-stranded structure of molecules like DNA or RNA.

Sticky Ends

Overhanging, single-stranded ends of DNA that are produced by the action of certain restriction enzymes, useful in molecular cloning to join DNA fragments together.

Introns

Non-coding sequences of DNA within a gene that are removed via RNA splicing during mRNA processing, leaving only exons to be translated into protein.
