RNA can form into double-stranded structures, such as during translation, when mRNA and tRNA molecules pair. DNA polymers are also much longer than RNA polymers; the 2.3m long human genome consists of ...

Researchers at the University of Chicago are developing a new technology that overcomes these challenges. By tagging each DNA or RNA molecule and allowing neighboring tags to interact, the technique ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a ...

The two nucleic acids DNA and RNA are named for the type of sugar complex that forms each molecule’s sugar-phosphate backbone–a kind of molecular thread holding the nucleotide beads together.

The DNA microscope is the first instrument that simultaneously reveals both where an RNA or DNA molecule is, down to individual cells, and its sequence.

DNA can be damaged in various ways by different things, such as exposure to UV rays, pollution, or chemotherapy. When both strands of the double-stranded DNA molecule are broken, it is known as a ...

Like DNA, it can form double strands with itself, as well as with DNA or RNA, making it a promising genetic system (Science, DOI: 10.1126/science.1174577).

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 ...

What’s driving the RNA age is this molecule’s dazzling versatility. Yes, RNA can store genetic information, just like DNA. As a case in point, many of the viruses (from influenza to Ebola to ...

We next used a double-tethered DNA curtain 29,30,31 to confirm that Cas9–RNA catalysed DNA cleavage in single-molecule assays.Although Cas9–RNA failed to dissociate from target sites even in ...

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life.

Simpler times: Did an earlier genetic molecule predate DNA and RNA? Date: January 18, 2012 Source: Arizona State University Summary: Scientists have described the Darwinian evolution of functional ...
