Amplified Ribosomal DNA Restriction Analysis - ARDRA Rationale and Procedure
... for the frequency of random occurrence of a Restriction site, a 4-bp sequence can occur once every 256bp ... A restriction enzyme having a recognition site of more than 4bp would be irrelevant with respect to a gene of approximately 1500bp such as that coding for the 16s ... A number of tetracutter Restriction enzymes are available in the market ...
Methylation - In Biology - Bacterial Host Defense
... adenosine or cytosine methylation is part of the restriction modification system of many bacteria ... A methylase is the enzyme that recognizes a specific sequence and methylates one of the bases in or near that sequence ... into the cell are degraded by sequence-specific restriction enzymes ...
Restriction Landmark Genomic Scanning
... Restriction Landmark Genomic Scanning (or RLGS) is a genome analysis method that allows for rapid simultaneous visualization of thousands of landmarks, or restriction sites ... Using a combination of restriction enzymes some of which are specific to DNA modifications, the technique can be used to visualize differences in methylation levels across the genome of a ... RLGS employs direct labeling of DNA, which is first cut by a specific series of restriction enzymes, and then labeled by a radioactive isotope (usually phosphorus-32) ...
DMNT - Classification - EC Classification

(N-6 adenine-specific DNA methylase) (A-Mtase) are enzymes that specifically methylate the amino group at the C-6 position of adenines in DNA ... in the three existing types of bacterial restriction-modification systems (in type I system the A-Mtase is the product of the hsdM gene, and in type III it is the ... These enzymes are responsible for the methylation of specific DNA sequences in order to prevent the host from digesting its own genome via its restriction enzymes ...

Famous quotes containing the word restriction:

    If we can find a principle to guide us in the handling of the child between nine and eighteen months, we can see that we need to allow enough opportunity for handling and investigation of objects to further intellectual development and just enough restriction required for family harmony and for the safety of the child.
    Selma H. Fraiberg (20th century)
