A new study published in Nature Structural & Molecular Biology reveals how the fundamental enzyme called DNA polymerase delta operates during DNA replication, making a copy of the genetic code that ...

DNA repair mechanism: HELQ helicase remodels stalled replication forks into stable structures, preventing harmful mutations under replication stress. Advanced imaging tool: RF-SIRF maps reversed forks ...

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

Researchers have identified HELQ as a key regulator of DNA replication stress responses, explaining why cells lacking the ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

Revising the structure and replication of DNA? Test your knowledge of the process and need for DNA replication with this Higher Biology quiz.

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that quantitatively detects and maps reversed DNA replication forks with ...

DNA is more than just a code—it’s a beautifully precise molecular structure that holds life’s instructions. Understanding its building blocks, base pairing rules, and replication fidelity helps us ...
