A sample implementation of teaching molecular structure of DNA in the classroom and the opinions of teacher candidates about it

The purpose of this study is to carry out sample classroom applications in the teaching of the molecular structure of deoxyribonucleic acid (DNA), which is the basis of the field of molecular biology, and obtaining the opinions of teacher candidates on these applications after they are completed. This is a basic, qualitative research study. The study was conducted in the fall semester of the academic year 2021-2022 at the Faculty of Education of a state university in Ankara. The participants from whom the data were collected were determined by the convenience sampling method. The research study group consisted of 15 teacher candidates, who were third-year biology students taking the molecular biology course. The interview form, developed by the researchers themselves and containing three questions, was the data collection tool for the study. Classroom applications used for the purposes of the study span a seven-year period. Teachings and other activities throughout the process were explained in detail. Thematic analysis, one of the qualitative analysis techniques, was used to analyze the data. In this study, an exemplary teaching practice/method was developed in DNA teaching. The findings showed that teacher candidates who took part in the application had positive views about the teaching of the subject and the process. In the future, various other teaching practices for other abstract concepts in biology can be developed and the views of prospective teachers explored. The effects of these classroom practices on the academic achievements, attitudes and motivation etc. of teacher candidates can be examined

The Effect of Ecological Footprint Education for Sustainable Life on Attitudes Towards Environmental Problems and Behavior Levels

The aim of this research is to investigate the effect of the ecological footprint education for sustainable life on attitudes towards environmental problems and behaviors levels in the 8 th grade science and technology class This research was carried out in the Science and Technology Lecture of the 8th class students of a secondary school which is in Ankara Kazan district, during 2013-2014 academic years. In this study, pre test–post test control group semi experimental design containing experimental and control groups was used. In the research, “Attitude Scale towards Environmental Problems” and “Behaviors Scale towards Environmental Problems” being pre-test and posttest for both groups were used as data collection tools. Finally, the applications of ecological footprint education towards sustainable life were seemed to be effective on students to change their attitude and behaviors against the environmental problems

Cryogenic X-ray crystallographic studies of biomacromolecules at Turkish Light Source “Turkish DeLight”

X-ray crystallography is a robust and powerful structural biology technique that provides high-resolution atomic structures of biomacromolecules. Scientists use this technique to unravel mechanistic and structural details of biological macromolecules (e.g., proteins, nucleic acids, protein complexes, protein-nucleic acid complexes, or large biological compartments). Since its inception, single-crystal cryocrystallography has never been performed in Türkiye due to the lack of a single-crystal X-ray diffractometer. The X-ray diffraction facility recently established at the University of Health Sciences, İstanbul, Türkiye will enable Turkish and international researchers to easily perform high-resolution structural analysis of biomacromolecules from single crystals. Here, we describe the technical and practical outlook of a state-of-the-art home-source X-ray, using lysozyme as a model protein. The methods and practice described in this article can be applied to any biological sample for structural studies. Therefore, this article will be a valuable practical guide from sample preparation to data analysis
