who first proposed the double helix structure of DNA. In this type of pairing, adenine (A) forms two hydrogen bonds with thymine (T) in DNA or uracil (U) in RNA, while guanine (G) forms three hydrogen ...

In reality, there is much more to the RNA story. However, in the half-century since the structure of DNA was first elaborated, scientists have learned that RNA does much more than simply play a ...

UMD researchers have discovered key mechanisms in gene regulation that could improve the design of RNA-based medicines.

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

alter their structure, and enable the binding of specific proteins that mediate various biochemical and cellular outcomes. The large size of RNA’s vocabulary relative to that of DNA’s is not ...

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 ...

NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.

Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, ...

If your genes could set an alarm clock, EZH1 might be the one ringing the bell. A new study has revealed how this ...
