the influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
The influence of formamide on thermal denaturation profiles of DNA and metaphase chromosomes in suspension.
Systematic photometric studies are presented to analyze the thermal denaturation behaviour with and without formamide of metaphase chromosome suspensions in comparison to DNA solutions. Temperature dependent hyperchromicity measurements at 256 nm and 313 nm were performed using an appropriately designed computer-controlled photometer device. Due to an upright optical axis, this allowed absorban...
متن کاملDNA Base Pair Mismatches Induce Structural Changes and Alter the Free Energy Landscape of Base Flip
Double-stranded DNA may contain mismatched base pairs beyond the Watson-Crick pairs guanine-cytosine and adenine-thymine. Such mismatches bear adverse consequences for human health. We utilize molecular dynamics and metadynamics computer simulations to study the equilibrium structure and dynamics for both matched and mismatched base pairs. We discover significant differences between matched and...
متن کاملDNA-directed base pair opening.
Strand separation is a fundamental molecular process essential for the reading of the genetic information during DNA replication, transcription and recombination. However, DNA melting in physiological conditions in which the double helix is expected to be stable represents a challenging problem. Current models propose that negative supercoiling destabilizes the double helix and promotes the spo...
متن کاملConstruction of a Synthetic Vector for Preparation of a 100 Base Pair DNA Ladder
DNA size markers are widely used to estimate the size of DNA samples on agarose or polyacrylamide gelelectrophoresis (PAGE). DNA markers can be prepared by mixing PCR products with definite sizes.Alternatively, they are prepared by restriction enzyme digestion of the genomic DNA of bacteriophages ornatural and synthetic DNA plasmids. The present study describes engineering of ...
