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 equally ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

Accurate chromosome segregation and cell division are central to maintaining genomic integrity and ensuring proper development and tissue homeostasis. These processes rely on a complex network of ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...

A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

A metabolic enzyme also binds and unwinds RNA to promote translation of cell cycle genes. This dual role links energy status ...

For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...
