RFLPs polymorphisms

Restriction fragment length polymorphism (RFLP) Polymorphism in length of DNA segments detected using a restriction enzyme, followed by separation using electrophoresis. 

The detection of restriction fi agment length polymorphisms (RFLPs) facilitates prenatal detection of hereditary disorders such as sickle cell trait, beta-thalassemia, infant phenylketonuria, and Huntington s disease. Detection of RFLPs involves cleavage of double-stranded DNA by restriction endonucleases, which can detect subtle alterations in DNA that affect their recognized sites. Chapter 40 provides further details concerning the use of PCR and restriction enzymes for diagnosis. 

The first human DNA SRM developed by NIST was designed in the late 1980 s to standardize Restriction Fragment Length Polymorphism (RFLP) procedures which at that time were very new developments in the application of DNA to forensic analysis.

Restriction fragment length polymorphism (RFLP) Variation between individuals in DNA fragment sizes cut by specific restriction enzymes. RFLPs are usually caused by mutation at a cutting site. 

In the formation of the zygote, all mitochondria are contributed by the ovum. Therefore, mtDNA is transmitted by maternal inheritance in a vertical, nonmendelian fashion. Strictly maternal transmission of mtDNA has been documented in humans by studies of restriction fragment length polymorphisms (RFLPs) in DNA from platelets. As exemplified by the disorders outlined above,...
