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

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

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.

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

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.

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 ...

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

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 ...

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 ...

EcDNA is made up of small, circular segments of DNA that form outside of chromosomes ... to gene expression in ecDNA formed by HPV and human DNA hybridization in oropharyngeal tumor cells.

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations - ...
