Double strand break repair notes

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. In human cells, there are two main DSB repair mechanisms: Homologous recombination (HR) and non-homologous end joining (NHEJ). HR relies on undamaged template … WebFeb 27, 2024 · Check for dirty or clogged filter cartridge.3. a) Remove filter cartridge in order to purge the air lock from the circulation pump intake. b) Hold a garden hose over filter …
