Amino acid transfers to tRNA, displacing AMP. Amino acid always is attached to adenine on 3' end of tRNA by its carboxyl group forming aminoacyltRNA. Initsiatsioon: 1. mRNA 2. Ribosoom 3.

eye infection, asthma and lung problems have decreased after installing a biogas plant According to the Biogas Users' Survey conducted in 2000 with 100 households, biogas can have positive impacts on the health of its users. Out of 42 respondents who had respiratory problems in the past, it was reported that the problem has improved for 34 of them. Similarly, those who had problems like asthma, eye infections and lung problems found that their problems had decreased after displacing dirtier fuels with biogas. If parasitic diseases had previously been common, the improvement in hygiene also has economic benefits (reduced working time). The more fully the sludge is digested, the more pathogens are killed. High temperatures and long retention times are more hygienic. The availability of biogas can have effects on nutritional patterns too. With easy access to energy, the number of warm meals may increase. Whole grain and
5. The cult. Impact of the Norman Conquest on the eng.lit.trad. The circumstances of writers changed greatly in the years after Conquest. The West-Saxon written standard collapsed and English writings were excluded, native traditions lost much of the status. During this period the English poetry and prose flourished mainly towards the margins of society. One of the most obvious changes was the introduction of the Latin- based Anglo-Norman language, displacing the Germanic-based Anglo-Saxon. Because the language of ruling classes. Brought the domination of French. But the natural tradition survived, vernacular literature is saved, since most of it was transmitted orally. Anglo-Saxon gradually evolved into ME. Several poems had survived, `Orrmulum' verse translation of parts of the Gospels, `the Owl and the Nightingale'- the first example of debate opposed positions, use every argument to attack and defend

The Jutes, along with some Angles, Saxons and Frisians, sailed across the North Sea to raid and eventually invade Great Britain from the late 4th century onwards, either displacing, absorbing, or destroying the native Celtic peoples there. 6.
