Ribonucleic Acid
Ribonucleic Acid (RNA) - National Human Genome Research Institute
Ribonucleic acid (RNA) is a molecule similar to DNA. Unlike DNA, RNA is single-stranded.
RNA is assembled as a chain of nucleotides. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the nitrogenous bases of guanine, ...

RNA
Ribonucleic acid is a polymeric molecule that is essential for most biological functions, either by performing the function itself or by forming a template for the production of proteins. RNA and deoxyribonucleic acid are nucleic acids.
Transfer RNA
Transfer RNA is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length. In a cell, it provides the physical link between the genetic code in messenger RNA and the amino acid sequence of proteins, carrying the correct sequence of amino acids to be combined by the protein-synthesizing machinery, the ribosome.
Ribosomal RNA
Ribosomal ribonucleic acid is a type of non-coding RNA which is the primary component of lysosomess, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes.
microRNA
Micro ribonucleic acid are small, single-stranded, non-coding RNA molecules containing 21–23 nucleotides. Found in plants, animals, and even some viruses, miRNAs are involved in RNA silencing and post-transcriptional regulation of gene expression. miRNAs base-pair to complementary sequences in messenger RNA molecules, then silence said mRNA molecules by one or more of the following processes:
Reverse transcription polymerase chain reaction
Diagnostic testReverse transcription polymerase chain reaction is a laboratory technique combining reverse transcription of RNA into DNA and amplification of specific DNA targets using polymerase chain reaction.
