The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism.

The process in which genetic material, in the form of chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets. In eukaryotes, chromosome segregation begins with the condensation of chromosomes, includes chromosome separation, and ends when chromosomes have completed movement to the spindle poles.

The process of producing non-motile spores, called conidia, via mitotic asexual reproduction in higher fungi. Conidia are haploid cells genetically identical to their haploid parent. They are produced by conversion of hyphal elements, or are borne on sporogenous cells on or within specialized structures termed conidiophores, and participate in dispersal of the fungus.

The assembly and arrangement of a cellular component that is composed of peptidoglycan and often chitin in addition to other materials and usually forms perpendicular to the long axis of a cell or hypha. It grows centripetally from the cell wall to the center of the cell and often functions in the compartmentalization of a cell into two daughter cells.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
