objective: in this paper, we have introduced topoisomerase inhibitors, mechanism of action and types of them. dna topoisomerases are ubiquitous enzymes that catalyze essential enzymes to solve the topological problems accompanying key nuclear processes such as dna replication, transcription, repair and chromatin assembly by introducing temporary single or double strand breaks in the dna. result...

Like the biological clock in the body, replication of each cell type (even different cells of the same organism) follows a timing program. Abnormal function of this timer could be an alarm for a disease like cancer. DNA replication starts from a specific point on the chromosome that is called the origin of replication. In contrast to prokaryotes in which DNA replication starts from a single ...

The Varicella-Zoster Virus (VZV) genome contains both cis-acting and trans-acting elements, which are important in viral DNA replication. The cis-acting elements consist of two copies of oriS, and the trans-acting elements are those genes whose products are required for virus DNA replication. It has been shown that each of the seven genes required for ori-dependent DNA synthesis of Herpes Simpl...

Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...

Significance CENP-A, the histone H3 variant that forms a unique centromeric chromatin, is essential for faithful chromosome segregation during mitosis. Inability to connect centromere mitotic spindle causes aneuploidy, hallmark of many cancers. In addition missegregation, fusions at (peri)centromeres are prevalent in cancers, but how such rearrangements arise remains unclear. Here, we identifie...
