The term "sequence analysis" in biology implies subjecting a DNA or peptide sequence to sequence alignment, sequence databases, repeated sequence searches, or other bioinformatics methods on a computer.
Sequence analysis in molecular biology and bioinformatics is an automated, computer-based examination of characteristically fragments, e.g. of a DNA-strand. It basically includes five biologically relevant topics:
The comparison of sequences in order to find similar sequences (sequence alignment)
Identification of gene-structures, reading frames, distributions of introns and exons and Regulatory elements
Prediction of protein structures
Genome mapping
comparison of
homologous sequences to construct a molecular phylogeny
In chemistry,
sequence analysis comprises techniques used to determine the sequence of a
polymer formed of several monomers. In molecular biology and genetics, the
same process is called simply "sequencing."
