Abstract: In this talk we first give a short introduction of the fractal theory, then give some graphic and numerical representation of DNA sequences and protein sequences. These representations include DNA walk models (one-dimensional DNA walk, two-dimensional DNA walk, higher-dimensional DNA walk), chaos game representation of biological sequences and their recurrent iterated function simulation, two-dimensional portrait representation of DNA sequences (fractal dimension of the fractal set for a given tag), onedimensional measure representation of biological sequences, Z curve representation of DNA sequences, number sequence of DNA sequences. We will also talk about how to use these representations to distinguish coding and non-coding DNA sequence from the same genome, or identify the species from the fragments of the genome, and discuss protein structural classes based on their amino sequences.
