The scientist who discovered hybridization and the "other" double helix describes what it meant to biology. By Alexander Rich Fifty-two years ago I was venturing to the basement of Cal Tech chemistry ...

ADAR1 converts adenosine to inosine in double-stranded RNA, a key process for preventing unwarranted immune responses, yet ...

Specifically, one strand of a double-stranded siRNA molecule can be incorporated into a complex called RISC. This RNA-containing complex can then inhibit transcription of an mRNA molecule that has ...

Although RNA is a single-stranded molecule, researchers soon discovered that it can form double-stranded structures, which are important to its function. In 1956, Alexander Rich—an X-ray ...

But Storici's team found that RNA can also help cells repair a severe form of DNA damage called a double-strand break, or DSB. A DSB means both strands of the DNA helix have been severed.

Scientists develop RNA-based technology to combat plant viruses, enhancing crop immunity and reducing losses worldwide.

Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases (Image: Wikimedia Commons, CC SA 3.0) Transfer RNA (tRNA) molecules are responsible for delivering ...

The message encoded in the messenger RNA is read by structures called ribosomes ... DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds ...

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 ...
