RNARNA may also stand for the Republic of New Africa Ribonucleic acid RNA is a nucleic acid consisting of a string of covalently-bound nucleotides. It is biochemically distinguished from DNA by the presence of an additional hydroxyl group, attached to each p RNA world hypothesisThe RNA world hypothesis proposes that RNA was, before the emergence of the first cell, the dominant, and probably the only, form of life. The phrase "The RNA World" was first used by Walter Gilbert in 1986. This hypothesis is supported by RNA's ability t RNA virusAn RNA virus is a virus that either uses RNA as its genetic material, or whose genetic material passes through an RNA intermediate during replication. For example, Hepatitis B virus is classified as an RNA virus, even though its genome is double-stranded RNA interferenceIn molecular biology, RNA interference RNAi is a relatively newly-discovered mechanism in which the presence of small fragments of double-stranded RNA ( dsRNA) whose sequence matches a given gene interferes with the expression of that gene. Overview RNAi RNA polymeraseThe enzyme RNA polymerase or RNAP is a nucleotidyltransferase that polymerises ribonucleotides in accordance with the information present in DNA. RNA polymerase enzymes are essential and are found in all cells of all organisms. RNAP accomplishes de novo s RNase HThe enzyme RNase H (EC 3. 4) is a ribonuclease that cleaves the 3'-O-P-bond of RNA in a DNA/RNA duplex to produce 3'-hydroxyl and 5'-phosphate terminated products. RNase H is an non-specific endonuclease and catalyzes the cleavage of RNA via an hydrolytic RNA splicing RNAS Yeovilton RNAse H
