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] ...

Japanese scientists detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu ...

A study reveals DNA and RNA epigenetics work together as a complementary system for precise gene regulation, crucial for cell ...

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 ...

Sunburn has traditionally been attributed to UV-induced DNA damage, but it turns out that this is not the full truth.

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 ...
