BioPHP

BioPHP detects and analyzes palindromic DNA sequences (inverted repeats, IRs) to enable genome-wide investigation of their roles in DNA–protein binding, DNA replication, and DNA transposition.

Key Features:

• Prime-number cumulative scoring algorithm: Uses a novel algorithm that represents nucleotide bases as prime numbers and computes a cumulative score to detect perfect inverted repeats with high precision.
• Detection of complex IRs: Implements methods that identify nested and overlapping inverted repeats and demonstrates higher accuracy than conventional string-comparison approaches.

Scientific Applications:

• Genome-wide IR analysis: Enables comprehensive detection and characterization of inverted repeats across prokaryotic and eukaryotic genomes.
• Study of DNA-related processes: Supports investigation of the involvement of palindromic sequences in DNA–protein binding, replication, and transposition.

Methodology:

The method transforms nucleotide bases into prime numbers and applies a cumulative scoring system implemented in MATLAB to detect perfect, nested, and overlapping inverted repeats, contrasting with traditional string-comparison techniques.
