Abstract

In this paper we construct a mathematical model for DNA replication based on Shannon's mathematical theory for communication. We treat DNA replication as a communication channel. We show that the mean replication rate is maximal with four nucleotide bases under the primary assumption that the pairing time of the G-C bases is between 1.65 and 3 times the pairing time of the A-T bases.
