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, ...
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, ...
Recent studies connect Y chromosome loss with several serious health conditions. These include heart disease, brain disorders ...
Chromosomes can vary in length and size, but they usually carry thousands of base pairs of DNA. While scientists have successfully edited the genomes of many creatures, most of those edits have been ...
Scientists have long known that cancer cells typically have extra chromosomes, but what exactly was the extra genetic material doing? New research from a team at Yale University has finally provided ...
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 ...
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 ...
On the flipside, if telomeres are too long, it can also spell trouble because cancer cells require long telomeres to become ...
In most mammals, females have two X chromosomes and males have one X and one Y chromosome in each of their cells. To avoid a double dose of X-linked genes in females, one of the Xs is silenced early ...
Damage to the ends of your chromosomes can create “zombie cells” that are still alive but can’t function, according to our recently published study in Nature Structural and Molecular Biology. When ...
Researchers have found that cancer cells contain shattered chromosomes that can allow a tumor to become more aggressive and help it resist chemotherapy drugs. Cancers evolve over several steps, and ...
