The pRSET-B vector encodes the β-lactamase gene (ampicillin resistance) and the phage f1 origin of replication for site-directed mutagenesis [ 5].
Both the kinetic and LC−MS/MS results obtained with Dpo4 are largely consistent with the mutagenic profiles obtained for replication of site-specifically modified shuttle vectors in E. coli and COS-7 cells (13).
M i is either zero (if the enzymatically active metabolic replicator set within the metabolic neighbourhood of site i is incomplete), or it is greater than or equal to 1. Obviously, M i = 0 implies C i = 0 (Eq. 3) and, consequently, no chance of replication for the replicator at site i.
Therefore, despite the dif sequence is located near the replication termination site for efficient CDR, the replication termination site is suggested to be at a site other than the dif site.
Therefore, although the dif sequence is located near the replication termination site for efficient CDR, the replication termination site is suggested to be at a site other than the dif site, as was recently shown in vivo [ 42].
It is concluded that the need for replication at single sites means that this approach has limited use for correlative purposes, although dating of sediments is important for understanding wider landscape evolution and patterns of human occupation.
The respiratory tract of poultry and gastrointestinal tract of waterfowl are replication sites for AIVs, and poultry are incubators for the progression of low-pathogenicity avian influenza (LPAI) virus into highly pathogenic avian influenza (HPAI) virus (4 – 6 ), usually through the acquisition of polybasic amino acids at the HA cleavage site.
This occurs during normal replication (for example at fragile sites) or during replication arrest induced by severe hypoxia as well as in response to certain DNA-damaging drugs, such as cross-linkers, antimetabolites and topoisomerase inhibitors (Hammond et al, 2002; Sogo et al, 2002; Zou and Elledge, 2003; Glover et al, 2005).
Lymph nodes are the specific replication sites for certain pathogenic viruses and bacteria [24] [29].
In fact, the incorporation of spacer sequences would even increase the replication cost, but this disadvantage could have been outweighed by the improvement of replication efficiency for these aa-binding sites (i.e. one turn of replication for a number of such sites).
This property is essential for the efficient replication of viruses in the low-pH intestinal tract, which is the main site of replication for these viruses.
