Nucleotide sequences repeated on both the 5' and 3' ends of a sequence under consideration. For example, the hallmarks of a transposon are that it is flanked by inverted repeats on each end and the inverted repeats are flanked by direct repeats. The Delta element of Ty retrotransposons and LTRs (long terminal repeats) are examples of this concept.

The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation.
Industry:Agriculture
A sequence of amino acids in a polypeptide or of nucleotides in genetic material that either has not changed or that has changed very little during an evolutionary period of time.

Industry:Agriculture
A theoretical representative nucleotide or amino acid sequence in which each nucleotide or amino acid is the one which occurs most frequently at that site in the different forms which occur in nature. The phrase also refers to an actual sequence which approximates the theoretical consensus.
