A summary of the number of reads and the composition of reads generated from the RNA-seq data is shown in Table 2 while steps taken to assemble the transcriptome from clean reads are shown in Figure 1.
Under the assumption that each WGS insert is sampled independently from the bacterial population - hence, the composition of reads represents that of the population - we discovered that the normal:flipped genotype ratio is 1 1, which is expected of a PV at equilibrium where the forward and reverse flipping rates are equal [ 16].
IRES-driven translation efficiency of the second cistron in bicistronic mRNAs is influenced by the composition of both reading frames [ 12].
Overall, horse reads recovered from the DNA phosphatase treatment were found to be slightly shorter than reads recovered without DNA phosphatase treatment and the base composition of these reads was similar to those recovered following the use of a 95°C denaturation temperature.
Nucleotide composition of the reads appears biased at their 5′end, with U being the first nucleotide on almost 60% of the reads.
Subsequently, the base composition of HQ reads was examined to rule out sequencing bias (Additional file 1: Figure S1).> -wrap-foot> readseads from control (BC), high temperature (BHS) and drought (BDS) stress libraries were subjected to various quality control parameters and reads that had contamination of adapter sequence or of low quality were eliminated.
Finally, variation in extraction techniques and/or sample preparation kits have been shown to affect the composition of sequence reads [ 8, 9].
The resulting running times and accuracies depend heavily on the exact composition of the read set with respect to the types of matches.
We did not observe any systematic divergence in nucleotide composition of sequenced reads between treated and untreated libraries (r 2 = 0.01, Additional file 1: Figure S1B-H).
In addition, specific sources of bias have been observed with tSMS, mostly as a result of the poly-A tailing and blocking reactions that are performed before sequencing and that skew the base composition of sequencing reads [ 15].
