SEMINAR
Speaker: Mr. Sunil Kumar

Title

Thermodynamics of self-replication

Date & Time: Thursday 11th October, 2018 at 4.00 PM

Venue: SSCU AUDITORIUM

Abstract:

Self-replication is an irreversible process carried out by living species through which, one produces copies of itself. Based on intuition, one can explain this as entropy driven process. In order to understand the thermodynamics of it, one must know the relation among heat production, growth rate, internal entropy and sustainability of the replicator.
In this talk I will formulate a general entropy change relation for irreversible processes. I will use the relation to explain the thermodynamic picture of various self-replicating systems like, exponentially growing cells, growth rate of polynucleotides & bacterial cell division.
Apart from entropy driven processes, I will use the aforementioned relation to explain self-assembly.
