If natural selection in a particular environment favored genetic systems that permitted the production of daughter ʺcellsʺ that were genetically dissimilar from the mother ʺcells,ʺ then one should expect selection for

I. polynucleotide polymerase with low mismatch error rates.

II. polynucleotide polymerases without proofreading capability.

III. batteries of efficient polynucleotide repair enzymes.

IV. polynucleotide polymerases with proofreading capability.

V. polynucleotide polymerases with high mismatch error rates.

I. Work done by the surrounding in case of infinite stage expansion is more than single stage expansion

II. Irreversible work is always greater than reversible work.

III. On an ideal gas in case of single stage expansion and compression system as well as surrounding are restored back to their original states

IV. If gas is in thermodynamic equilibrium is taken from state A to state B, by four successive single stage expansions.
