DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases. (Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base ...

All five nucleobases that make up DNA and RNA have now been detected in meteorite samples ... as terrestrial soil and other environments also contain nucleotide bases. “I think [the researchers] ...

Scientists at the University of Toronto studying the hermaphroditic worm Caenorhabditis elegans found that amyloid-like ...

RNA is often compared to a copy from a reference book, or a template, because it carries the same information as its DNA template but is not used for long-term storage. Each ribonucleotide base ...

Because RNAs are so central to our biology, they are also drivers of a wide array of diseases. Defects in how RNA is produced ...

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...

By virtue of complementary base- pairing, this action creates a new strand of mRNA that is organized in the 5' to 3' direction. As the RNA polymerase continues down the strand of DNA, more ...

Repair reactions involve the excision of chemically altered or mispaired bases from the DNA duplex ... An analogous process occurs during chromosomal DNA replication, whereby the 5’-RNA segments that ...
