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

An individual's genome is the sum total of their genes. DNA and RNA strands vary in length from less than two dozen base ...

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 ...

However, in the half-century since the structure of DNA was first ... one strand of a double-stranded siRNA molecule can be incorporated into a complex called RISC. This RNA-containing complex ...

During DNA replication, the complementary base pairing ensures faithful copying of the genetic material. In RNA, cytosine also pairs with guanine. However, RNA is typically single-stranded and serves ...

Researchers led by François Fuks - Laboratory of Cancer Epigenetics, ULB Faculty of Medicine, ULB-Cancer Research Center and Jules Bordet Institute, H.U.B. - have discovered a new mechanism which ...

Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally.

Enzymes called RNA polymerases transcribe DNA into RNA. RNA is the intermediary that carries the information contained within DNA to the ribosomes, where the genetic information is synthesized into ...

In this review of RNA therapies, we paint an overview of what’s going on in a field that is addressing a number of diseases.

Double-stranded DNA helices are great for storing genetic ... carry out all sorts of functions to keep cells alive. What makes RNA unique is that these molecules can do a bit of both.

Sunburn has traditionally been attributed to UV-induced DNA damage. However, a new study reveals that RNA, another vital cellular molecule, plays a major role in triggering acute sunburn reactions.
