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.Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found ...

Standard Process - Ribonucleic Acid (RNA)
Ribonucleic Acid (RNA), derived from yeast, supports cell replication, growth, and protein synthesis.* Promotes healthy cellular growth and development

RNA | Definition, Structure, Types, & Functions ...
RNA is a single-stranded nucleic acid polymer of the four nucleotides A, C, G, and U joined through a backbone of alternating phosphate and ribose sugar residues. It is the first intermediate in converting the information from DNA into proteins essential for… RNA structure. RNA typically is a single-stranded biopolymer.

Ribonucleic Acid (RNA) Structure & Function
The nucleotides of nucleic acids are linked together by covalent bonds between phosphate of one nucleotide and sugar of next. These linked monomers become the phosphate-sugar backbone of ribonucleic acids, and nitrogenous bases extend from this phosphate-sugar backbone like teeth of a comb.

Explainer: what is RNA? - The Conversation
Our genetic material is encoded in DNA (deoxyribonucleic acid).DNA is famous. But you may also have also heard of RNA (ribonucleic acid).So, what is RNA, and what is it good for? Quite a lot really.

Exploring Life's Origins: What is RNA?
Another major difference between DNA and RNA is that DNA is usually found in a double-stranded form in cells, while RNA is typically found in a single-stranded form, as shown in the illustration above.

Small interfering RNA - Wikipedia
Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA molecules, 20-25 base pairs in length, similar to miRNA, and operating within the RNA interference (RNAi) pathway. It interferes with the expression of specific genes with complementary nucleotide sequences by degrading mRNA after transcription, preventing translation

Chem4Kids.com: Biochemistry: DNA
DNA Details DNA stands for deoxyribonucleic acid.It is special, because it holds the code for every cell in your body. That's right. Every cell in your body uses DNA as an instruction manual.

RNA Synthesis - Chemistry Encyclopedia - number, molecule
Biochemists refer to RNA synthesis as transcription .Transcription is the process of synthesizing ribonucleic acid (RNA). Synthesis takes place within the nucleus of eukaryotic cells or in the cytoplasm of prokaryotes and converts the genetic code from a gene in deoxyribonucleic acid ( DNA ) to a strand of RNA that then directs protein synthesis.

What is RNA? (with picture) - wisegeek.com
Ribonucleic acid (RNA) is a chain of nucleotides present in the cells of all life. This chain has a number of important functions for living organisms, ranging from the regulation of gene expression to assistance with copying genes.
