    Type of biological prediction

    Protein structure prediction is the inference of the three-dimensional structure of a protein from its amino acid sequence—that is, the prediction of its secondary and tertiary structure from primary structure.
    Structure prediction is different from the inverse problem of protein design.
    Protein structure prediction is one of the most important goals pursued by computational biology; and it is important in medicine and biotechnology.

    An array of protein tandem repeats is defined as several adjacent copies

    An array of protein tandem repeats is defined as several adjacent copies having the same or similar sequence motifs.
    These periodic sequences are generated by internal duplications in both coding and non-coding genomic sequences.
    Repetitive units of protein tandem repeats are considerably diverse, ranging from the repetition of a single amino acid to domains of 100 or more residues.
