Generating and manipulating transgenic animals using transposable elements

Transposable elements, or transposons, have played a significant role in the history of biological research. They have had a major influence on the structure of genomes during evolution, they can cause mutations, and their study led to the concept of so-called "selfish DNA". In addition, transposons have been manipulated as useful gene transfer vectors. While primarily restricted to use in invertebrates, prokaryotes, and plants, it is now clear that transposon technology and biology are just as relevant to the study of vertebrate species. Multiple transposons now have been shown to be active in vertebrates and they can be used for germline transgenesis, somatic cell transgenesis/gene therapy, and random germline insertional mutagenesis. The sophistication of these applications and the number of active elements are likely to increase over the next several years. This review covers the vertebrate-active retrotransposons and transposons that have been well studied and adapted for use as gene transfer agents. General considerations and predictions about the future utility of transposon technology are discussed

The methodological strategies in the teaching learning proccess of English language in the 8Th grade students at Villa Libertad School from the period of March and October of 2014

Currently students are dealing with a non-native language which is English. When they are in high school, this could be one reason for the lack of interest in learning a different language; another reason could be the native language that interferes in the learning process. Therefore, teachers represent a major role in the English teaching process, as they are responsible for motivating students to learn the language at the same time teachers are responsible for the lack of students’ motivation. This research focuses on analyzing the main factors that affect the teachinglearning process; in fact, the research focuses on the influence of the English learning process. But the most important aspect is to analyze how the English reading skill is developed and how it affects the teaching-learning process in the eighth grade students at Villa Libertad School. Finally, in this research will be discussed a possible solution for the classroom conditions in order to improve and motivate students to learn the English reading skill because it is considered that the classroom conditions are very important for having a good environment for the reading acquisition
