This group also clarified that Shugoshin controls DNA replication (the process by which DNA makes a copy of itself during cell division) in subtelomeres as well as higher - order structure of chromosomes.

Using a mouse model, the team also demonstrated that two processes during neurodevelopment are regulated by the gene: proliferation — the replication of neuronal stem cells that have the potential to become multiple different kinds of cells, including neurons — and migration — the movement of neurons to specific locations in the brain during development.

This suggests that random errors occurring during DNA replication in normal stem cells are a major contributing factor in cancer development.

Cyclin D is synthesized during the first stage of cell replication and is believed to help drive the complex, multi-stage process, including interaction with the retinoblastoma (Rb) protein, whose function is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide.

The dance of chromosomes is tightly controlled during cell replication to preserve the genetic makeup of cells.

During meiosis, the genome of a diploid germ cell, which is composed of long segments of DNA packaged into chromosomes, undergoes DNA replication followed by two rounds of division, resulting in haploid cells called gametes.

The shortening of telomeres is a process that occurs naturally in the body each time that a cell divides: during cell division the DNA, which is tightly packaged into chromosomes, must be duplicated but the DNA - copying machinery design itself, prevents the full replication of the ends of the chromosomes.

In a September paper in the Journal of Chemical Physics, he reported the theoretical minimum amount of dissipation that can occur during the self - replication of RNA molecules and bacterial cells, and showed that it is very close to the actual amounts these systems dissipate when replicating.

Holstege says the other remarkable finding was that the mutations within the blood cells were harmless — all resulted from mistaken replication of DNA during van Andel - Schipper's life as the «mother» blood stem cells multiplied to provide clones from which blood was repeatedly replenished.

Partly based on his MIT Ph.D. thesis research performed in yeast, Sheltzer suspects aneuploidy causes errors in DNA replication, as well as problems with chromosome segregation during cell division.

It corrects mutations that arise during the replication of the genome during cell division.

Somatic Cell Mutants Resistant to Retrovirus Replication: Intracellular Blocks during the Early Stages of Infection

The Mattiroli group studies chromatin dynamics during DNA replication to understand how the epigenetic information is faithfully propagated during cell division.

Some bacteria have a loop of DNA, and two interlocking rings of nucleic acid can appear as an intermediate during cell replication.
