RNA editing was first discovered within the mitochondria of kinetoplastid protozoans, where it has been shown to be extensive. [30] For example, some protein-coding genes encode fewer than 50% of the nucleotides found within the mature, translated mRNA. Other RNA editing events are found in mammals, plants, bacteria and viruses.
He characterized the different forms of nucleic acid, DNA from RNA, and found that DNA contained adenine, guanine, thymine, cytosine, deoxyribose, and a phosphate group. [ 1 ] He was born into a Litvak (Lithuanian Jewish) family as Fishel Rostropovich Levin in the town of Žagarė in Lithuania , then part of the Russian Empire , but grew up in ...
In 1977, introns and RNA splicing were discovered in both mammalian viruses and in cellular genes, resulting in a 1993 Nobel to Philip Sharp and Richard Roberts. Catalytic RNA molecules were discovered in the early 1980s, leading to a 1989 Nobel award to Thomas Cech and Sidney Altman.

The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes. Other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
U.S. scientists Victor Ambros and Gary Ruvkun won the 2024 Nobel Prize in Medicine on Monday for the discovery of microRNA and its crucial role in how multicellular organisms grow and live.
The discovery by Victor Ambros and Gary Ruvkun may help yield treatments for diseases like cancer ... DNA codes that make up genes lead to RNA sequences that cells then turn into proteins ...
It was this subsequent discovery that led to the identification and naming of DNA as a substance distinct from RNA. Friedrich Miescher (1844–1895) discovered a substance he called "nuclein" in 1869.
