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 ...

Some cells can turn cancerous when they divide, due to chromosomes getting “lost” in the process. In a new study, researchers at the University of Warwick have uncovered what happens to these lost ...

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 ...

Humans contain 46 chromosomes (23 from their mother, and 23 from their father) in each of their body cells. This image shows duplicated chromosomes from a human male. Summary Scientists at the Sloan ...

New findings shed light on how chromosomes manage the various pushing and pulling forces generated when cells divide. Specifically, researchers show that chromosomes resist being punctured by the ...

Many of us are familiar with typical diagrams of a chromosome, which is sometimes depicted like a stubby X. While that picture may resemble what is seen after some chromosome staining methods, in the ...

Cancer cells with extra chromosomes depend on those chromosomes for tumor growth, a new study reveals, and eliminating them prevents the cells from forming tumors. The findings, said the researchers, ...

Scientists first read the human genome, a three-billion-letter biological book, in April 2003. Since then, researchers have steadily advanced the ability to write DNA, moving far beyond single-gene ...

Non-coding DNA is essential for both humans and trypanosomes, despite the large evolutionary divergence between these two species.

Scientists have provided an explanation of how chromosomes undergo structural changes during cell differentiation. The human genome is made up of 46 chromosomes, each of which has a length of about ...
