RNA metabolism during a developmental process. Modeling by Boolean functions and automata theory.

Area of Science:

• Developmental Biology
• Computational Biology
• Molecular Genetics

Background:

• Insect development involves complex regulation of RNA synthesis and degradation.
• Understanding macromolecule dynamics is crucial for deciphering developmental processes.
• Previous models have not fully captured the interplay of RNA metabolism during differentiation.

Purpose of the Study:

• To develop a computational model simulating rRNA and polyA(+)mRNA evolution during insect wing disc differentiation.
• To investigate the role of 'clock pulses' in regulating RNA accumulation and degradation.
• To incorporate diapause and emergence from diapause into the RNA metabolism model.

Main Methods:

• A two-section model combining logical genetic regulation networks and automata theory.
• Simulation of RNA synthesis and degradation rates using logical and analogical components.
• Integration of 'clock pulses' to represent developmental stages and biological rhythms.

Main Results:

• The model successfully accounted for complex variations in RNA classes during differentiation.
• Calculated synthesis and degradation rates align with those reported in other differentiation systems.
• The model accurately computed the timing of developmental events and RNA synthesis stages.

Conclusions:

• The developed model provides a computational framework for understanding RNA metabolism during development.
• The model is applicable to diverse developmental processes exhibiting significant RNA synthesis variations.
• This approach offers a computationally efficient method for analyzing RNA molecule regulation.
