The SOS response is a global response to DNA damage in which the cell cycle is arrested and DNA repair and mutagenesis are induced. The system involves the RecA protein ( Rad51 in eukaryotes). The RecA protein, stimulated by single-stranded DNA, is involved in the inactivation of the repressor ( LexA) of SOS response genes thereby inducing the ...

DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. [ 1] In human cells, both normal metabolic activities and environmental factors such as radiation can cause DNA damage, resulting in tens of thousands of individual molecular lesions per cell per day.

Section 504 loans and grants. Section 504 loans and grants are a USDA rural housing repair program authorized under Section 504 of the Housing Act of 1949. Under current regulations, rural homeowners with incomes of 50% or less of the area median may qualify for the Rural Housing Service (RHS) direct loans to repair their homes. Loans are ...
Site-directed mutagenesis is a molecular biology method that is used to make specific and intentional mutating changes to the DNA sequence of a gene and any gene products. Also called site-specific mutagenesis or oligonucleotide-directed mutagenesis, it is used for investigating the structure and biological activity of DNA, RNA, and protein ...
A double-strand break repair model refers to the various models of pathways that cells undertake to repair double strand-breaks (DSB). DSB repair is an important cellular process, as the accumulation of unrepaired DSB could lead to chromosomal rearrangements, tumorigenesis or even cell death. [1] In human cells, there are two main DSB repair ...

Templates are not expanded in the edit summary field, so you can't use it there directly. Instead, use your sandbox , or Special:ExpandTemplates , or another test page to expand the template, and then paste from there into the edit summary of the article needing attribution repair, using a dummy edit so the summary will be saved.
