Finally, splice sites (sequences immediately surrounding the exon-intron boundaries) can also be considered as consensus sequences. Thus a consensus sequence is a model for a putative DNA binding site: it is obtained by aligning all known examples of a certain recognition site and defined as the idealized sequence that represents the ...
Phrap was routinely used in some of the largest sequencing projects in the Human Genome Sequencing Project and is currently one of the most widely used DNA sequence assembly programs in the biotech industry. Phrap uses Phred quality scores to determine highly accurate consensus sequences and to estimate the quality of the consensus sequences.
A consensus logo is a simplified variation of a sequence logo that can be embedded in text format. Like a sequence logo, a consensus logo is created from a collection of aligned protein or DNA/RNA sequences and conveys information about the conservation of each position of a sequence motif or sequence alignment [1] [4].
A contig (from contiguous) is a set of overlapping DNA segments that together represent a consensus region of DNA. [1] In bottom-up sequencing projects, a contig refers to overlapping sequence data (); [2] in top-down sequencing projects, contig refers to the overlapping clones that form a physical map of the genome that is used to guide sequencing and assembly.

In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences. [1] Aligned sequences of nucleotide or amino acid residues are typically represented as rows within a matrix.
The TATA box consensus sequence is TATAWAW, where W is either A or T. In molecular biology, the TATA box (also called the Goldberg–Hogness box) [1] is a sequence of DNA found in the core promoter region of genes in archaea and eukaryotes. [2] The bacterial homolog of the TATA box is called the Pribnow box which has a shorter consensus sequence.
Early de novo sequence assemblers, such as SEQAID [2] (1984) and CAP [3] (1992), used greedy algorithms, such as overlap-layout-consensus (OLC) algorithms. These algorithms find overlap between all reads, use the overlap to determine a layout (or tiling) of the reads, and then produce a consensus sequence.
Circular consensus sequencing (CCS) is a DNA sequencing method that is used in conjunction with single-molecule real-time sequencing to yield highly accurate long-read sequencing datasets with read lengths averaging 15–25 kb with median accuracy greater than 99.9%.
