In addition, many bacteria possess restriction-modification systems enabling them to distinguish between the cell's own DNA and foreign DNA entering the cell.
Only 55 (1.5%) oligonucleotides were found to possess the restriction site.
First, to allow for easy cloning of ORFs into donor vectors, we modified the multiple cloning site on the donor vector to possess two restriction endonuclease sites that occur infrequently in mammalian cDNAs.
In several cases, REases efficiency can depend on the number of restriction-modification sites, for example Ecl18kI, EcoRII, etc. are more active when DNA possesses several restriction sites [ 58, 59].
MACE consequently allows for preparation of libraries with varying read lengths and provides additional information regarding transcripts that do not possess an according restriction site for anchoring.
The choices people make, given the information they possess and the restrictions they face, constitute the subject matter of economics.
Although all TRIM family proteins have RBCC domains, it remains elusive whether they possess similar late-restriction activities.
The Helicobacter pylori is present in the human stomach [23] and is known to possess many diverse restriction-modification systems [24], [25].
Three of these were examined by restriction digestion using BamHI and all possessed the expected restriction fragments of 0.7, 3.0 and 7.1 kb (one representative is shown in Figure 5).
Of these sequences, 93.66% (19,360) possessed the NlaIII restriction site (CATG) used in the tag library construction.
In addition, the CJIE2 of the genome of C. jejuni IHV116292 possesses a KpnI restriction site (in the gene immediately upstream of the Cj0594 homologue) which is not present in the CJIE2 of C. jejuni 4031.
