32 P-label is introduced by incoming dGT 32 P molecule. The arrows indicate the sites of enzymatic hydrolysis. The bases of the template DNA strand are designated as clear boxes, and the bases in the ...

The sugar-phosphate backbone forms the structural framework of nucleic acids, like DNA and RNA, and is composed of alternating sugar and phosphate groups.

Researchers in China have developed a new method that allows them to insert long stretches of DNA into a genome. The process, named GRAND editing, is one of a handful of new systems aimed at using two ...

Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate ...

Carnegie Mellon University researchers have developed a synthetic molecule that can recognize and bind to double-stranded DNA or RNA under normal physiological conditions. The molecule could provide a ...

Researchers at Purdue's Birck Nanotechnology Center have shown how "nanopore channels" can be used to rapidly and precisely detect specific sequences of DNA as a potential tool for genomic ...

DNA is usually known as a biological carrier of information. However, scientists can use DNA as a building material to make microscopic structures. These DNA structures can self-assemble through ...

Chemists have made a discovery that supports a surprising new view of how life originated on our planet. They demonstrated that a simple compound called diamidophosphate (DAP), which was plausibly ...

The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of ...

The clever use of a specially modified primer during PCR allows the rapid and inexpensive gel electrophoresis-based purification of single-stranded DNAs. Single-stranded DNA (ssDNA) molecules, which ...

DNA can signal the presence of or predisposition to a slew of diseases, including cancer. The ability to flag down these clues, known as biomarkers, allows medical professionals to make critical early ...
