Are nucleic acids left or right handed



Chirality is a property of asymmetry important in several branches of science. The word "chirality" comes from the Greek χειρ, "hand", a familiar chiral object. Object or system is chiral if it differs from its mirror image, that is, it can not be imposed on him. Conversely, the mirror image achiral object, such as a sphere, cannot be separated from the object. A chiral object and its mirror image are called enantiomorphs Greek "opposite forms" or, when referring to molecules, enantiomers. Not a chiral object is called achiral sometimes amphichiral and can be superimposed on its mirror ima ...


Renault Dauphine

Renault Dauphine is a rear-wheel drive economy car-class produced by Renault in one body style – a three-box, 4-door sedan – as the successor to the Renault 4CV, with over two million were manufactured during its production 1956-1967. Along with such cars as the Citroen 2CV, Volkswagen beetle, Morris minor, mini and Fiat 500, the Dauphine pioneered in the modern European economy car. Renault sold numerous leisure options including a luxury version, the Ondine Renault sport version, Dauphine Gordini and Ondine Gordini, 1093 factory racing model, and the Caravelle / floride For, and the Daup ...


Alfa Romeo 105/115 Series Coupes

Alfa Romeo 105 and 115 series coupes were different cars produced by Italian company Alfa Romeo from 1963 until 1977, on the basis of cropped bottoms in the saloon Julia. They were the successors of the Giulietta sprint coupe.


Exclusive right

In Anglo-Saxon law, an exclusive right, or exclusivity, de facto, immaterial prerogative existing in law to perform an action or acquire a benefit and to permit or deny others the right to perform the same action or to acquire the same benefit. This "prerogative" is valid exclusive right. The period of restriction on the use of state or sovereign authority. Exclusive rights is a form of monopoly. Exclusive rights can be established by law or in accordance with contractual obligations, but the scope of applicability will depend on the extent to which other associated instrument establishing ...


Peptide nucleic acid

Peptide nucleic acid is an artificially synthesized polymer similar to DNA or RNA. It was invented by Peter E. Nielsen, Michael Egholm, Rolf Berg, and OLE Buchardt in 1991. Synthetic peptide nucleic acid oligomers have been used in recent years in molecular biology procedures, diagnostic tests, and antimyeloma therapy. Due to their higher Binding strength it is not necessary to design PNA oligomers for use in these roles, which usually require oligonucleotide probes of 20-25 bases. The main concern is the length of the PNA oligomers is the provision of specifics. PNA oligomers also show gr ...

Jose Nuñez (right-handed pitcher)

Jose Jimenez is a former major League baseball pitcher. He was signed by the Kansas city royals as a free agent in 1983 and has supplied major League baseball for the Toronto blue jays and Chicago cubs. Núñez is currently a pitching coach in the Minor League system of the Milwaukee Brewers. After leaving the big leagues, Nunez enjoyed a long and prosperous career in Asia, playing for the UNI-President lions, 1993-1995, 1996-1997 Fukuoka Daiei hawks, Taichung Agan in 1998 and the Hanwha eagles in 2001. He shared Taiwans professional baseball record of winning the most games in a single seas ...

Picric acid

Picric acid is an organic compound with the formula 3 with 6 n 2nd. Its IUPAC name is 2.4.6-trinitrophenol. The name of "picric" comes from the Greek πικρός, which means "bitter", reflecting its bitter taste. This is one of the most acidic phenols. Like other nitrated organic compounds, picric acid is an explosive, so its primary use. It is also used in medicine and dyes.


Exercise Armageddon

Exercise Armageddon was the military doctrine of the Republic of Ireland in 1970. The aim of the exercise was to study, plan and rehearse in detail the intervention of the armed forces in Northern Ireland in order to ensure the safety of the population ".
