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] ...

Unlike traditional microscopes that use light or lenses, DNA microscopy creates images by calculating interactions among ...

Over billions of years, complex molecules like DNA, RNA and proteins formed in ... the researchers from TUM and LMU used a ...

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 ...

and several nitrogen-containing bases. Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA ...

Whether it is a microbe, a rose, or a dolphin, any form of life gets its building and operating instructions from the molecule of life, DNA ... different chemical bases, or nucleotides: adenine ...
