A few nucleotide sites of nuclear exons that flank introns are often conserved. A hypothesis has suggested that these sites, called "proto-splice sites," are remnants of recognition signals for the insertion of introns in the early evolution of eukaryotic genes. This notion of proto-splice sites has been an important basis for the insertional theory of introns. This hypothesis predicts that the...

This paper presents a novel semi-automatic translation method for the Phaistos Disk that had no convincing translation for over a century. The method uses for a recently discovered connection between the Phaistos Disk symbols and other ancient scripts, including the Old Hungarian alphabet. The connection between the Phaistos Disk script and the Old Hungarian alphabet suggested the possibility t...

The 20 known transforming (onc) genes of retroviruses are defined by sequences that are transduced from cellular genes termed protooncogenes or cellular oncogenes. Based on these sequences, viral onc genes have been postulated to be transduced cellular cancer genes, and proto-onc genes have been postulated to be latent cancer genes that can be activated from within the cell to cause virus-negat...

Protoporphyrinogen oxidase (Protox) inhibitors and other com pounds which block o r stim­ ulate the porphyrin pathway can cause sufficient levels o f porphyrins to accum ulate in plant tissues for severe photodynam ic dam age to occur. The gross sym ptom ology for all o f these p o r­ phyrinogenic herbicides is similar. Porphyrin accum ulation induced by three porphyrinogenic herbicides acifluo...

Abstract From a linguistic standpoint, Proto-Japonic and Proto-Koreanic are assumed to have split off the Transeurasian languages in southern Manchuria. The idea that came earlier than chronological scheme means language first entered Korean Peninsula, from there spread Japanese archipelago at beginning of Yayoi period, around ninth century BC, while arrival Korea is associated with rolled rim ...

Vanillin is an interesting corrosion inhibitor because of its safe use and high solubility inwater. The effect of vanillin on the corrosion inhibition of carbon steel in 1.0 Mhydrochloric acid solution has been studied using potentiodynamic polarization,electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques.The effect of temperature on the rate of corrosion in th...

The effect of Mentha spicata L. extract on the corrosion behaviour of carbon steel in 1.0 M HCl solution was investigated using polarization, electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (IE). The effect of temperature on the rate of corrosion ...
