Since topoisomerases, enzymes known to remove replication-related stress ... mother cell started as a cell with 46 chromosomes, these must be duplicated before division take place.

Before a cell can divide into two independent ... That has been the greatest challenge to studying how the replication of our own chromosomes takes place and consequently what is going wrong ...

Right before a cell starts to divide ... cell division by first creating copies of chromosomes like most human cells and has a very fast replication cycle, all of which facilitated the study.

This replication process puts tremendous ... the new chromosomes form two rings linked through each other. The new chromosomes must unlink before the cell divides into two cells.

Late replication of Xi was proposed to ... 0.08 μg ml −1) before preparation of mitotic chromosomes according to standard procedures. Halogenated nucleotides were detected using anti-BrdU ...

The initiation of chromosome replication is exquisitely regulated in both time and location. It has been estimated that there are 200-400 autosomal replication sequence elements (ARSs) in the yeast ...

To build you, and then keep you alive, the DNA in your cells needs to undergo replication every day to duplicate your chromosomes before cell division. Decades of research have determined that DNA ...
