Area of Science:

  • Computational Biology
  • Genomics
  • Bioinformatics

Background:

  • Promoters are crucial genomic regions regulating gene expression.
  • Identifying cis-acting sites within promoters is essential for understanding gene regulation.
  • Short consensus sequences, or cis-acting sites, are characteristic features of promoters.

Purpose of the Study:

  • To develop an evolutionary method for recognizing the makeup and position of cis-acting sites in genomic sequences.
  • To apply the developed method for promoter prediction in the human genome.
  • To explore the potential of the method for discovering gene-specific cis-acting sites and co-regulated genes.

Main Methods:

  • Combines Finite State Automata (FSA) with Genetic Programming (GP) for sequence discovery.
