In molecular biology , restrictionfragmentlengthpolymorphism , or RFLP commonly pronounced rif lip , is a technique that exploits variations in homologous DNA sequences. It refers to a polymorphism biology difference between samples of homologous DNA molecules that come from differing locations of restriction site restriction enzyme sites , and to a related laboratory technique by which these segments can be illustrated.

A restrictionfragment is a DNA fragment resulting from the cutting of a DNA strand by a restriction enzyme restriction endonucleases , a process called restriction. Each restriction enzyme is highly specific, recognising a particular short DNA sequence, or restriction site, and cutting both DNA strands at specific points within this site. Most restriction sites are Palindromic sequence palindromic , the sequence of nucleotides is the same on both strands when read in the 5 to 3 direction , and are four to eight nucleotide s long. Many cuts are made by one restriction enzyme because of the chance repetition of these sequences in a long DNA molecule, yielding a set of restriction fragments. A particular DNA molecule will always yield the same set of restriction fragments when exposed to the same restriction enzyme. Restriction fragments can be analyzed using techniques such as gel electrophoresis or used in recombinant DNA technology. Image Restriction enzyme.jpg thumb Illustration of typical restriction enzyme cleavage. In recombinant DNA technology specific restriction endonucleases are used that will isolate a particular gene and cleave the sugar phosphate backbones at different points retaining symmetry , so that the double stranded restriction fragments have single stranded ends. These short extensions, called sticky ends can form hydrogen bond ed base pairs with complementary sticky ends on any other DNA cut with the same enzyme such as a bacterial plasmid . In agarose gel electrophoresis , the restriction fragments yield a band pattern characteristic of the original DNA molecule and restriction enzyme used, for example the relatively small DNA molecules of viruses and plasmids can be identified simply by their restrictionfragment patterns.

In genetics , chromosomal polymorphism is a condition where one species contains members with varying chromosome counts or shapes. Polymorphism biology Polymorphism is a general concept in biology where more than one version of a trait is present in a population. In some cases of differing counts, the difference in chromosome counts is the result of a single chromosome undergoing fission, where it splits into two smaller chromosomes, or two undergoing fusion, where two chromosomes join to form one. This condition has been detected in many species. Trichomycterus davisi , for example, is an extreme case where the polymorphism was present within a single Chimera genetics chimeric individual. ref cite journal journal Genet. Mol.
