We have named the encoded representation 'nuID', for nucleotide universal identifier.
Overall, the study has developed novel methodologies in numerical representation for improved nucleotide to numeric mapping, spectral analysis for effective period-3 spectral value computation, and thresholding for more accurate classification of unknown exon and intron sequences of fixed and arbitrary length.
The K-Quaternary Code III (Code 15) [C, G, A, T] = [-j, -1, 1, j] is identical to the pentanary code in [20] (with [20] specifies that x[n] = 0 for an unknown nucleotide at position n) which was derived for the three-dimensional DNA walk for graphical representation of nucleotide sequences.
We present a novel approach for interactive representation of nucleotide substitutions and modifications in the transcribed genome.
In an SNP locus only 2 nucleotides are observed, and a single bit is sufficient for the representation of nucleotide variants such that 0 encodes the major allele and 1 encodes the minor allele.
Therefore, an interface mode with a distinct drawing style for nucleotide representation was developed.
For ease of representation, the procedure will be illustrated for nucleotide sequences, which is also the scale for which unidirectional USM is equivalent to the CGR procedure.
Our study has provided a proof-of-principle that reduced representation shotgun sequencing (RRS) [47] is a tool that can be used for nucleotide polymorphism discovery with prokaryotes.
For nucleotide and amino acid sequences see [Additional file 1]. Figure 1 Schematic representation of the block units for the four SELP copolymers, where Sx represents the number of silk-like blocks and Ey the number of elastin-like blocks.
CLustalW was used for nucleotide sequence alignment.
