DNA replication is a fundamental process for a cell to ensure that an accurate copy of its genetic material is transmitted to daughter cells at each cell division. Challenges to DNA replication ...

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 ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

The radiation in space is not great for biological health. Space radiation is known to damage DNA. Many types of human cells have to frequently divide to replace cells that are worn out, old, or ...

Huge sections of the human genome are made up of highly repetitive sequences, areas where bases like ATATAT repeat in very long strings. For many years, scientists wrote these repetitive sequences off ...

SAN DIEGO--(BUSINESS WIRE)--Boundless Bio, a next-generation precision oncology company developing innovative therapeutics directed against extrachromosomal DNA (ecDNA) in oncogene amplified cancers, ...

DNA-folding nanorobots can manufacture limitless copies of themselves By Loz Blain December 08, 2023 Tiny nano-robots have been developed that can grab tiny snippets of DNA and assemble them into new ...

Error-prone DNA replication and repair may lead to mutations and cancer in individuals who inherit a mutant copy of the BRCA1 gene, according to a new study by Weill Cornell Medicine investigators.
