The chemical origin of life on Earth is a puzzle that scientists have been trying to piece together for decades. Many hypotheses have been proposed to explain how life came to be and what chemical and ...

As a molecular biologist, I always enjoy reading articles concerning DNA and RNA. Your excellent article in the April 3, 2023, issue of C&EN (page 18) titled “The Promise of Peptide Nucleic Acids” ...

To obtain high-quality, purified nucleic acids, scientists can use several different methods, including phenol-chloroform extraction, cesium chloride/ethidium bromide (CsCl/EtBr) gradient ...

Researchers have created a new polymer to deliver DNA and RNA-based therapies for diseases. For the first time in the industry, the researchers were able to see exactly how polymers interact with ...

DNA is the poster child for high-specificity binding. As long as their base sequences match, two complementary strands of DNA can navigate through a sea of biomolecules, find each other, and hold fast ...

A recent Science paper discusses the utilization of a previously reported synthetic Escherichia coli to produce virus-resistant synthetic polymers for future drug production applications. By ...

Biopolymers include any polymers produced by living cells, constructed from repeating monomers that are linked together to form a longer chain. Examples of monomers include nucleic acids, sugars, ...

The biosecurity risks associated with an unregulated industry became evident when, in 2006, a Guardian reporter successfully ordered parts of the smallpox genome through the mail. Although ordering ...
