.What is the procedure for DNA replication? ANS. DNA replication is the process by which a double-stranded DNA molecule is copied, resulting in th...Read full What is the role of DNA polymerase in the life of eukaryotic cells? ANS. There is a wide variety of these enzymes in eukaryotic...
Finally, we sought to address the functional relevance of the replication dynamics and fork remodeling for reprogramming to totipotency. Terminally differentiated somatic cells can be reprogrammed to totipotency upon transplantation into enucleated oocytes51,52. However, this process is inefficient and ofte...
DNA replication, also known assemi-conservative replication, is the process by which DNA is doubled. This is an important process taking place within the dividing cell. In this article, we shall discuss thestructureof DNA, the steps involved inDNA replication(initiation, elongation and termination...
are reprogrammed during early embryogenesis to establish full developmental potential. Previous studies have suggested that the paternal genome is actively demethylated in the zygote while the maternal genome undergoes subsequent passive demethylation via DNA replication during cleavage...

Eukaryotic DNA replication refers to the process by which eukaryotic cells duplicate their DNA, involving the binding of the origin recognition complex (ORC) to replication origins, the formation of pre-replicative complexes (pre-RCs), and the initiation of DNA replication by helicase activity. This...
【8】Fork coupling directs DNA replication elongation and termination(叉耦合指导DNA复制伸长和终止):研究发现DNA复制叉以成对形式耦合,控制着复制伸长并确定了复制的终止。 DNA复制是一个精密的过程,涉及在特定DNA起源点启动和在两个复制叉相遇时终止的步骤。在真核细胞中,与大肠杆菌不同,有数百到数千个复制起...
一、由单链断裂导致的复制叉坍塌(replication fork collapse)或由DNA复制受阻导致的复制叉断裂(replication fork breakage)是造成DSB的重要原因(复制叉坍塌或断裂几乎在E.coli的每个细胞周期中都会自然发生。在静止期E.coli中,复制叉可以R环为基础组建,并可在基因组中常见的自发单链断裂处坍塌。)。单链断裂可由单链...
DNA replication forks are tightly controlled by a large protein network consisting of well-known core regulators and many accessory factors which remain functionally undefined. In this study, we report previously unknown nuclear functions of the actin-bi
Nucleosome assembly during DNA replication is tightly coupled to ongoing DNA synthesis. This process, termed DNA replication-coupled (RC) nucleosome assembly, is essential for chromatin replication and has a great impact on both genome stability maintena
