Abstract:
Protein synthesis is the final step of gene expression in all cells. In order to understand the regulation of this process, it is important to have an accurate model that incorporates the regulatory steps. The model presented in this paper is composed of set of differential equations which describe the dynamics of the initiation process and its control, as well as peptide elongation, starting with the amino acids available for peptide creation. A novel approach for modeling the elongation process permits useful prediction of protein production and consumption of energy and amino acids, as well as ribosome loading rate and ribosome spacing on the mRNA.

Ribosome Structure and Assembly
Ribosomes are composed of ribosomal RNA (rRNA) and proteins. In eukaryotes, rRNA is transcribed from genes in the nucleolus—a part of the nucleus that specializes in ribosome production. Within...

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
