The phrase "a number of replication" is not correct in English.
It should be "a number of replications" when referring to multiple instances of replication in a scientific or research context.
Example: "The study included a number of replications to ensure the results were reliable."
Alternatives: "several replications" or "multiple replications".
The Adenovirus (Ad) dl309 mutant, which lacks several E3 region genes, has been used as the backbone for a number of replication selective cytopathic Ads designed to treat tumours.
First, viral vectors have the tendency to lose the inserted sequences after a number of replication rounds or plant passages [ 14].
The fact that Mcm1 regulates the expression of a number of replication initiation factors may be related to our observation that there is a peak of nucleosome dynamics around ARSs (Fig. 2).
A number of replication defects that map to the snoRNP component Sik1 (also known as Nop56) have been reported [ 50], while human snoRNP associated proteins have been co-purified with proteins involved in DNA replication and transcription [ 51].
Large populations are desirable for association mapping studies in order to obtain a high power to detect genetic effects of moderate size [ 10, 23]; however, there is a high cost associated with genotyping and phenotyping such populations, particularly for traits requiring extensive field trials, chemical or biochemical assays and a number of replications for measures' reliability.
The dynamics of resistant mutants depends on a number of virus replication parameters such as the fitness values, the number of available target cells and mutation/recombination rates.
It appears that the primary factor in establishing the rate of starvation-induced killing is a number of chromosomal replication events in a bacterial population.
While the reviewed literature rendered mixed results about the efficacy of a number of psychotherapies, replication and extension of the current body of knowledge is needed including comparisons of the efficacy and acceptability of adapted with non-adapted interventions.
Given that cysts are a non-replicative dormant phase of the live cycle, it's not surprising that there are a number of chromosome replication genes that are significantly down-regulated late (72 hours to 96 hours) in cyst development.
In an earlier microarray study of estrogen-responsive genes, Lobenhofer and colleagues [ 39] observed an increase in the expression of a number of DNA replication fork genes, including those that have been shown to be regulated by the E2F transcription factor.
From our qRT-PCR array, we identified a number of HBV-replication-related regulators that were up-regulated by knockdown of each target gene, such as HNF1A [ 23] or HNF1B, as well as other transcription factors for HBV replication that were down-regulated, such as PPARGC.
