RNA - Wikipedia
Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes.RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life.
RNA | biochemistry | Britannica.com
RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses.
Ribonucleic Acid (RNA) Structure & Function
Ribonucleic acid (RNA) functions as genetic messengers and builders of the cellular world. Here are the basics of RNA and gene expression.
Exploring Life's Origins: What is RNA?
RNA folding is mediated by base-pairing interactions along different regions of a single-stranded RNA. This animations shows a theoretical model of how folding might occur.
What is RNA? | RNA Society
Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: “DNA makes RNA makes protein”.
Pearson - The Biology Place
Concept 6 Review RNA. RNA, made by polymerizing ribonucleotides, forms single-stranded molecules used in information processing. An RNA consists of a "backbone" of alternating units of phosphate and ribose.
RNA - definition of RNA by The Free Dictionary
Short for ribonucleic acid. The nucleic acid that determines protein synthesis in all living cells and the genetic makeup of many viruses. RNA consists of a single strand of nucleotides in a variety of lengths and shapes and is mainly produced in the cell nucleus. ♦ Messenger RNA is RNA that carries genetic information from the cell nucleus ...
Rna | Define Rna at Dictionary.com
Rna definition, ribonucleic acid: any of a class of single-stranded molecules transcribed from DNA in the cell nucleus or in the mitochondrion or chloroplast, containing along the strand a linear sequence of nucleotide bases that is complementary to the DNA strand from which it is transcribed: the composition of the RNA molecule is identical ...
16S ribosomal RNA - Wikipedia
16S ribosomal RNA (or 16S rRNA) is the component of the 30S small subunit of a prokaryotic ribosome that binds to the Shine-Dalgarno sequence.The genes coding for it are referred to as 16S rRNA gene and are used in reconstructing phylogenies, due to the slow rates of evolution of this region of the gene.
