Z-curve

[edit]

The Z-curve method is a bioinformatics algorithm for genome analysis. The Z-curve is a three-dimensional curve that constitutes a unique representation of a DNA sequence, i.e., for the Z-curve and the given DNA sequence each can be uniquely reconstructed from the other. [1] The resulting curve has a zigzag shape, hence the name Z-curve. The Z-curve method has been used in many different areas of genome research, such as replication origin identification[2], ab initio gene prediction[3], isochore identification[4], genomic island identification[5] and comparative genomics.[6]
