Didn't you say that the water at 39 degrees is more dense than water at its freezing point? I think the reason organisms would die is because the water already starting to structure in a crystal form, when it starts to freeze into ice. This probably why it kills the organisms, is because the water ceases to allow the organism to function at those temperatures.
Two potential functions that eukaryotic cells perform to regulate transcription are DNA methylation: a process of epigenetics that participates in the regulation of the gene expression in two ways, directly impeding the union of the transcription factors, and indirectly propitiating the closed structure of the chromatin, and Histone acetylation, enzymes that acetylate conserved lysine residues in histones by transferring an acetyl group from an acetyl-CoA molecule, to form ε-N-acetyl lysine, is extensively associated with an open chromatin structure and therefore accessible to transcription factors, which increases gene expression.

A division of your immune system called cell mediated immunity is charged with stopping viral infections. The main actors of that are called cytotoxic T cells who, when they encounter a cell that is displaying viral antigens on its surface, binds to the cell and releases toxic substances called perforins and granzymes that destroy and digest the viral infected cell.
