Building a chromosome from scratch may sound like science fiction, but scientists have actually done it-and made it work. In ...

They exist as circular pieces of DNA in the nuclei of tumor cells outside chromosomes. Transcription of the amplified ecDNA genes can promote oncogenic processes, such as the increased expression ...

have identified rules that tell cells how to fold DNA into the tightly packed, iconic X-shaped chromosomes formed during mitosis that help ensure the accurate passing of genetic information between ...

Researchers have discovered how telomeres (the protective caps at the end of chromosomes) help prevent abnormal genetic ...

Engineers and biologists at Dartmouth College have found that, just like word order affects meaning in a sentence, the ...

Scientists at the Institute of Cancer Research in London and Linköping University in Sweden have discovered how cells prevent ...

An advanced genomic analysis of a multigenerational family is providing new knowledge about genetic mutations and their ...

Medulloblastoma is one of the most common malignant tumors of the central nervous system (CNS) in children and adolescents.

A "Jeopardy!" show recently asked what animal had the most chromosomes. This month's River Life column tells us more about answer: the hermit crab.

Before cells divide, they replicate the double-stranded DNA of each chromosome ... the end caps of chromosomes that safeguard the genetic material from damage and normally shorten with aging.

Medulloblastomas, brain tumors in children, are thought to develop between the first trimester of pregnancy and the end of the first year of life. Researchers have now analyzed the genetic changes of ...
