Quantitative approaches to problems of eukaryotic gene expression. First, DNA fragments spanning the human mitochondrial 12S rRNA gene position at 1066 to 1497 and the 16S rRNA gene from 2582 to 3081 were amplified by PCR using the universal primers M13U12S-F (forward) and M13U12S-R (reverse) for the mitochondrial 12S rRNA gene21,22 and M13U16S-F (forward) and M13U16S-R (reverse) for the mitochondrial 16S rRNA gene, as listed in Table 2. Currently, most analysis, especially the identification of conserved regions, relies heavily on Multiple Sequence Alignment and its various heuristics such as progressive alignment, whose run time grows with the square of the number and the length of the aligned sequences and requires significant computational resources.

Cap analysis gene expression for high-throughput analysis of transcriptional starting point and identification of promoter usage. & Wasserman, W. W. TFBS: computational framework for transcription factor binding site analysis. Specifically, after analyzing the 100 BLAST hit results (Table 3) for both the 12S and 16S rRNA PCR amplicon sequences from each animal tissue and known DNA sample, we have found that all hits occurred in the mitochondrial genomes, rather than the nuclear genomes. volume4, Articlenumber:4089 (2014) Natl Acad. Clamp, M. et al. 2, 13 (2003). Assessment of the predictions via a 5-fold cross-validation method revealed that predictions based on features derived from a single structure perform similarly to ones based on homologous sequences, while combining sequence and structural features was optimal in terms of accuracy (0.755) and Matthews correlation coefficient (0.476). It has been previously reported that noncoding elements that are deeply conserved throughout the evolution of vertebrates have particular DNA signatures (Ovcharenko et al., 2004; Prabhakar et al., 2006) and are tightly linked to developmental and transcription factor genes (Woolfe et al., 2005).
