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

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

Arthur Kornberg compared DNA to a tape recording of instructions that can be copied over and over. How do cells make these near-perfect copies, and does the process ever vary? In reality ...

A breakthrough in safely delivering therapeutic DNA to cells could transform treatment for millions suffering from common chronic diseases like heart disease, diabetes, and cancer. A new process ...

Every human has unique DNA (except for identical twins who share the same DNA, as they both came from the same initial cell). Forensic scientists use the unique nature of DNA to help catch criminals.

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 ...
