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 ...

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 ...

Since the 1980s, the design and synthesis of molecular machines has been identified as a grand challenge for molecular engineering. Robots are an important type of molecular machine that automatically ...

A novel chip automates the reaction cascades occurring between molecules inside DNA to carry out complex mathematical calculations. The field of DNA computing has evolved by leaps and bounds since it ...

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 ...

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 ...

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 ...

A DNA nano-harvester stays on its track inside tumor cells, measuring cancer aggressiveness by detecting a key microRNA biomarker.

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 ...
