Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a heat stimulus, a temperature stimulus above the optimal temperature for that organism.

The process carried out by a cell that restores the biological activity of an unfolded or misfolded protein, using helper proteins such as chaperones.

Any process in which DNA is protected from damage by, for example, oxidative stress.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nucleoid. The nucleoid is the region of a bacterial cell, virion, mitochondrion or chloroplast to which the DNA is confined.

Any process that activates or increases the frequency, rate or extent of transcription regulatory region DNA binding.

The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The region of a bacterial cell to which the DNA is confined.
