A number of satisfactory methods are available for the electron microscopy of nicleic acids. These methods concentrated on fragments of nuclear, viral and mitochondrial DNA less than 50 megadaltons, on denaturation and heteroduplex mapping (Davies et al 1971) or on the interaction between proteins and DNA (Brack and Delain 1975). Less attention has been paid to the experimental criteria necessary for spreading and visualisation by dark field electron microscopy of large intact issociations of DNA. This communication will report on those criteria in relation to the ultrastructure of the (approx. 1 x 10-14g) DNA component of the kinetoplast from Trypanosomes. An extraction method has been developed to eliminate native endonucleases and nuclear contamination and to isolate the kinetoplast DNA (KDNA) as a compact network of high molecular weight. In collaboration with Dr. Ch. Brack (Basel [nstitute of Immunology), we studied the conditions necessary to prepare this KDNA Tor dark field electron microscopy using the microdrop spreading technique.

This research is intended to know the effectiveness of quantum reading model by printing media with yen basis in reading concept learning to students of grade 4th elementary school. The problems are: profile of students reading concept competences, the learning process of reading concept, the learning process of reading concept by quantum reading model by printing media with yen basis, the effectiveness of quantum reading model by printing media with yen basis in reading concept learning, and students response of quantum reading model by printing media with yen basis.The trouble-shooting is by use quantum reading model by printing media with yen basis by assumption: if students need to do something therefore will be easily to motivate them in learning and get a better result.Population in this research is Grade 4th Students of elementary school at Sumber Regency, Cirebon. The sample is determined by purposive sampling. The objects in this research are quantum reading model by printing media with yen basis and students reading concept competences. Instruments in this research are sheets of questionnaire, sheets of learning observation, and reading concept competence test. Data that are collected are learning process and data of students reading concept competences. Collected data are analyzed by descriptive statistic analyze.Result of this research are: (1) the competences of students reading concept are good, (2) the learning process are done with students actively, (3) quantum reading model by printing media with yen basis can increase students activity and learning result, (4) quantum reading model by printing media with yen basis is effective to use in reading concept learning, and (5) the students response to reading concept learning by use quantum reading model by printing media with yen basis is very good.Base on the result of this research, get to be proposed for teacher to use quantum reading model by printing media with yen basis to increase students reading concept competence as one of alternative technique in learning, because it is able to motivate, grow the students interest, and increase students creativities to increase students reading concept competences.
