As climate change outpaces the ability of ecosystems to adapt, scientists are turning to conservation genomics to guide ...

When bacteria cells replicate, they do so a little differently than human cells do. They don’t undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

A sample collected by the Hayabusa 2 spacecraft from the spinning top-like asteroid contained the nucleobases adenine, guanine, cytosine, thymine, and uracil. When you purchase through links on our ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Our studies show the levels of type I topoisomerases are increased in human papillomaviruses (HPV)-positive cells, leading to enhanced levels of DNA breaks and activation of DNA repair pathways.

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Is it the invasion of the genome snatchers? Just in case the idea of aliens walking around in human skin suits wasn’t frightening enough. An outlandish study asserts that aliens might have abducted us ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Drs Ursula A. Matulonis and Joyce F. Liu discuss targeting DNA damage and repair and replication stress in endometrial cancer. Drs Ursula A. Matulonis and Panagiotis A. Konstantinopoulos discuss ...

Andrés Aguilera's laboratory, in collaboration with that of Ralf Wellinger (both professors in the Department of Genetics at the University of Seville in CABIMER) and with PharmaMAR, has identified ...

Extrachromosomal DNA (ecDNA) is a unique form of circular DNA that exists outside of normal chromosomes. Found exclusively in tumor cells, it often carries cancer-promoting genes (oncogenes) and is ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...
