In 2012 a modified RAD tagging method called double digest RADseq (ddRADseq) was suggested. [10] [11] By adding a second restriction enzyme, replacing the random shearing, and a tight DNA size selection step it is possible to perform low-cost population genotyping.
A restriction map is a map of known restriction sites within a sequence of DNA.Restriction mapping requires the use of restriction enzymes.In molecular biology, restriction maps are used as a reference to engineer plasmids or other relatively short pieces of DNA, and sometimes for longer genomic DNA.
Restriction digest is most commonly used as part of the process of the molecular cloning of DNA fragment into a vector (such as a cloning vector or an expression vector).The vector typically contains a multiple cloning site where many restriction site may be found, and a foreign piece of DNA may be inserted into the vector by first cutting the restriction sites in the vector as well the DNA ...
Specific restriction endonucleases are used to digest DNA. The RFLP molecular marker is specific to a single fragment. Along with alleic RFLP markers, a molecular-weight size marker, in this case a DNA marker, [30] is also included on an electorphoresed agarose gel. The DNA marker allows for the size of the restriction fragments to be estimated.

HaeIII along with other restriction enzymes were discovered in 1970 by Werner Arber and Matthew Meselson. The HaeIII methyltransferase also known as MTase gene from Haemophilus aegyptius (recognition sequence: 5′-GGCC-3′) was made into Escherichia coli (E.coli) in the plasmid vector pBR322.
New England Biolabs (NEB) is an American life sciences company which produces and supplies recombinant and native enzyme reagents for life science research. [2] It also provides products and services supporting genome editing , synthetic biology and next-generation sequencing . [ 3 ]
Depiction of the restriction enzyme (endonuclease) HindIII cleaving a double-stranded DNA molecule at a valid restriction site (5'–A|AGCTT–3').. In biochemistry, a nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phosphodiester bonds that link nucleotides together to form nucleic acids.
