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 ...

Homology-directed repair (HDR) is a mechanism in cells to repair double-strand DNA lesions. [1] The most common form of HDR is homologous recombination . The HDR mechanism can only be used by the cell when there is a homologous piece of DNA present in the nucleus , mostly in G2 and S phase of the cell cycle .
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 ...
