Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

CDT1 inhibits the helicase activity of the MCM complex, thereby suppressing nascent strand synthesis in DNA replication in cultured human cells. This action results in fork collapse and DNA damage, ...

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, ...

Gerlinde Bigga does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond ...

“The laws of inheritance are quite unknown,” Charles Darwin acknowledged in 1859. The discovery of DNA’s shape altered how we conceived of life itself. The X-ray crystallography by Rosalind Franklin ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. The cassette tape. A staple of the Walkmans, car stereos, and ...

DNA, deoxyribonucleic acid, carrying encoded genetic information at molecular level, is the most significant discovery in the history of genetics. Previous researches on DNA included topics of bases, ...

A new study shows that DNA forms coils under stress, not the tangled knots that scientists expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

The Age of AI will rely on massive volumes of data that can be easily stored and retrieved—and bioscience may have an ingenious solution. A scientist examines a DNA (deoxyribonucleic acid) profile on ...

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 ...

Cancer’s genetic fingerprints may lurk in people’s blood long before they find out about the disease. It’s possible to spot tumor DNA more than three years before a person is diagnosed with cancer, ...

Fifteen years after the discovery of a new type of human, the Denisovan, scientists discovered its DNA in a fossilized skull. The key? Tooth plaque. By Carl Zimmer When Qiaomei Fu discovered a new ...
