1. Restriction
Artificial or natural control against widening of a channel, with or without construction.

2. Restriction enzyme (restriction endonuclease)
A protein that recognizes specific, short nucleotide sequence s and cuts DNA at those sites. Bacteria contain over 400 such enzyme s that recognize and cut over 100 different DNA sequences.

3. Restriction enzyme cutting site
A specific nucleotide sequence of DNA at which a particular restriction enzyme cuts the DNA. Some sites occur frequently in DNA (e.g., every several hundred base pair s), others much less frequently (rare-cutter; e.g., every 10,000 base pairs).

4. Restriction enzymes
A series of enzymes that attach to DNA molecules at specific nucleotide sequences and cut both strands of DNA at those sites. A bacterial enzyme that cuts DNA at a specific recognition sequence. This is a bacterial defense against viral DNA and plasmid DNA and is now used as an important tool in biotechnology.

5. Restriction fragment
A section of double-stranded DNA which is produced by the action of a restriction endonuclease on the parent DNA.

6. Restriction fragment length polymorphism (RFLP)
Variation between individuals in DNA fragment sizes cut by specific restriction enzyme s; polymorphic sequence s that result in RFLPs are used as marker s on both physical map s and genetic linkage map s. RFLPs are usually caused by mutation at a cutting site. See marker .

7. Restriction fragment length polymorphism (RFLP)
A heritable difference in DNA fragment length and fragment number; passed from generation to generation in a codominant way.
