Answer :

Self replication of living cells occurs by the catalytic action of Proteins.

The biological process that results in the creation of an exact or comparable clone of itself is known as self-replication. DNA replication takes place during cell division and can be passed on to progeny during reproduction.

Proteins are the main metabolites used as the catalyst in the biological and chemical reactions. Enzymes made up of protein has main role in enzyme catalysis, which decrease the activation energy, thus increase the rate of reaction.
