Mung bean nuclease (Nuclease MB) is a nuclease derived from sprouts of the mung bean (Vigna radiata) that removes nucleotides in a step-wise manner from single-stranded DNA molecules (ssDNA) and is used in biotechnological applications to remove such ssDNA from a mixture also containing double-stranded DNA (dsDNA).
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 ...
The principal function of restriction enzymes is the protection of the host genome against foreign DNA, but they may also have some involvement in recombination and transposition. [1] Like most type II restriction enzymes, BglII consists of two identical subunits that form a homodimer around the DNA double helix.
The new procedure involves digesting DNA with a particular restriction enzyme (for example: SbfI, NsiI,…), ligating the first adapter, called P1, to the overhangs, randomly shearing the DNA into fragments much smaller than the average distance between restriction sites, preparing the sheared ends into blunt ends and ligating the second ...
RRBS uniquely uses a specific restriction enzyme to enrich for CpGs. MspI digestion, or any restriction enzyme that recognizes CpG's and cuts them, produces only fragments with CG’s at the end. [2] This approach enriches for CpG regions of the genome, so it can decrease the amount of sequencing required as well as decrease the cost. [2]
In molecular biology, XhoI is a type II restriction enzyme EC that recognise the double-stranded DNA sequence CTCGAG and cleaves after C-1. [1] Type II restriction endonucleases are components of prokaryotic DNA restriction-modification mechanisms that protect the organism against invading foreign DNA.
The restriction modification system (RM system) is found in bacteria and archaea, and provides a defense against foreign DNA, such as that borne by bacteriophages.. Bacteria have restriction enzymes, also called restriction endonucleases, which cleave double-stranded DNA at specific points into fragments, which are then degraded further by other endonucleases.
Micrococcal nuclease (EC 3.1.31.1, S7 Nuclease, MNase, spleen endonuclease, thermonuclease, nuclease T, micrococcal endonuclease, nuclease T', staphylococcal nuclease, spleen phosphodiesterase, Staphylococcus aureus nuclease, Staphylococcus aureus nuclease B, ribonucleate (deoxynucleate) 3'-nucleotidohydrolase) is an endo-exonuclease that preferentially digests single-stranded nucleic acids.
