RNA ribonucleic

Aldopentoses have three chirality centers and a total of 23 = 8 possible stereoisomers, or four d,l pairs of enantiomers. These four pairs are called ribose, arabinose, xylose, and lyxose. All except lyxose occur widely. r>Ribose is an important constituent of RNA (ribonucleic acid), t-arabinose is found in many plants, and D-xylose is found in wood. 

The nucleic acids DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are biological polymers that act as chemical carriers of an organism s genetic information. Enzyme-catalyzed hydrolysis of nucleic acids yields nucleotides, the monomer units from which RNA and DNA are constructed. Further enzyme-catalyzed hydrolysis of the nucleotides yields nucleosides plus phosphate. Nucleosides, in turn, consist of a purine or pyrimidine base linked to Cl of an aldopentose sugar—ribose in RNA and 2-deoxyribose in DNA. The nucleotides are joined by phosphate links between the 5 phosphate of one nucleotide and the 3 hydroxyl on the sugar of another nucleotide. 

Extracts from 152 plant species, representing 46 different families, were screened for effects on tobacco mosaic virus (TMV) replication in cucumber cotyledons. Twenty species have shown enough activity to warrant further study. Several members of the Caprifoliaceae family increased virus replication. An extract of Lonicera involucrata enlarged the virus lesions in local lesion hosts and produced a thirty fold increase in virus titer, but had no effect on virus replication in systemic hosts. The active material appears to affect the virus defense mechanism of local lesion hosts. An extract of common geranium is an active virus inhibitor. It inactivates TMV and TMV-RNA (ribonucleic acid) in vitro by forming non-infectious complexes. In vivo, it also inhibited starch lesion formation in cucumber cotyledons incited by TMV infection. 

Deoxyribonucleic acid (DNA, Fig. 3-13) is the genetic material of all organisms, including plants, animals, and microorganisms. (Some viruses lack DNA, but use RNA (ribonucleic acid) in its place.) DNA carries all the hereditary information of the organism and is therefore replicated and passed from parent to offspring. RNA is formed on DNA in the nucleus of the...

Along with stomach, bile, and lactic acids, there are many other acids in the human body These include, but are not limited to, nucleic acids, amino acids, fatty acids, and vitamins such as folic and ascorbic acids. Nucleic acids, including RNA (ribonucleic acid) and DNA (deoxyribonucleic acid), are long chains of phosphates and sugar to which nucleotide bases are attached. The phosphate molecules in the backbone of RNA and DNA are derived from phosphoric acid. Therefore, DNA is very weakly acidic.

RNA RNA (ribonucleic acid) is an information encoded strand of nucleotides, similar to DNA, but with a slightly different chemical structure. In RNA, the letter U (uracil) is substituted for T in the genetic code. RNA delivers DNA s genetic message to the cytoplasm of a cell where proteins are made. 

Only two nucleic acids exist. They are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). The structural complexity of nucleic acids falls far short of that of proteins. Like proteins, however, nucleic acids are polymers, with nucleotides being the monomer units.

During the process of transcription, the information stored in a gene s DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
