Researchers at Washington University School of Medicine in St. Louis have revealed the structure of a key protein involved in ...

His lab studies how Origin Recognition Complexes -- ORCs -- coordinate DNA duplication. They discovered how our cells assemble and disassemble ORCs during the cell division cycle.

During division, cells must duplicate their genetic material (or DNA) and ensure identical copies are passed along to the daughter cells. The entire process must work perfectly.

Chromatin and nuclear structure influence where and when DNA replication initiates, whereas the replication process itself disrupts chromatin and challenges established patterns of genome regulation.

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

Revise structure and replication of DNA for your Higher Human Biology exam with Bitesize Scotland interactive practice quizzes covering feedback and common errors.

However, this would be impossible with DNA in spaghetti form. That’s why the DNA strands are wrapped as tightly as possible ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study by EMBL ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it ...

Nearly all these inserted elements have been silenced by our cells' defense mechanisms over time, but a few, nicknamed "jumping genes," can still move around the human genome like viruses. Just ...
