Abstract

Chromatin is a highly dynamic structure that acts alternately as a substrate and a template in a number of critical biological processes. Modification of chromatin is pertinent and is responsible for a number of nuclear processes, including DNA repair, replication, transcription, and recombination. The purpose of this review is to discuss specific interactions between chromatin remodeling, DNA repair, and transcription. These areas are demonstrated to share commonality, particularly with a number of key molecules that appear to have roles in a number of pathways. The implications of pathway cross-over and communication form a seamless continuation of genomic integrity and stability.

摘要

染色质是一种高度动态的结构,在许多关键的生物学过程中交替充当底物和模板。染色质修饰至关重要,负责许多核过程,包括DNA修复、复制、转录和重组。本综述的目的是讨论染色质重塑、DNA修复和转录之间的特定相互作用。这些领域被证明具有共性,特别是有一些关键分子似乎在许多途径中发挥作用。途径交叉和交流的意义构成了基因组完整性和稳定性的无缝延续。
