To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies.

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

Credit: Professor Jessica Downs. Scientists have found a genetic mutation that results in cancer cells being able to tolerate having an abnormal number of chromosomes – a condition which normally ...

Human cells typically receive 46 chromosomes, 23 from each parent. The team discovered nonviable embryos started with the 46-chromosome set, but then passed down incorrect numbers of chromosomes ...

This finding led to a model of cancer growth called “oncogene addiction.” When investigating how an extra copy of chromosome 1q might promote cancer, the researchers found that multiple genes ...

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 ...
