DNA Replication vs IRAKU

The DOST Courseware is a locally-produced, all-original Filipino highly interactive multimedia educational application packages that are conceptualized, digitized and produced as spearheaded by the Science Education Institute (SEI-DOST) in partnership with the Advanced Science and Technology Institute (ASTI-DOST) and in cooperation with the Department of Education (DepEd), Philippine Normal University (PNU) and University of the Philippines-National Institute for Science and Mathematics Education (UP-NISMED), which aims to develop information and communication technology learning innovation to support the upgrading and improvement of science and mathematics education in the country. The DOST Courseware are provided for free to schools and are also made available online as supplemental resources for teachers and student as a fun and interactive approach to e-learning and blended learning. The Grade 7 DOST Courseware is composed of 120 lessons overall, 73 lessons in Science where it covered the domains on: Matter; Force, Motion and Energy, Living Things and Their Environment and Earth and Space while the 60 lessons in Mathematic covered the domains on: Numbers and Number Sense, Patterns and Algebra, and Geometry. The Grade 8 DOST Courseware is composed of 118 lessons overall, 61 lessons in Science where it covered the domains on: Parts and Functions, Ecosystems, Heredity: Inheritance and Variation of Traits, Structures and Functions, Biodiversity, and Evolution, while the 57 lessons in Mathematics covered the domains on: Linear Equations, Quadratic Equations, Rational Algebraic Equations, Integral Exponents, Radicals, Arithmetic Sequence and Geometric Sequence. The themes of the courseware for Grades 7 and 8, Magicademy, Freddy’s Lab and D’nayao will surely amuse the users as they explore these distinct worlds while learning at the same time.

IRAKU is an educational app that lets you learn genetics, DNA and evolution through moving simulations. Every mode unfolds in 4 steps and ends with a real example from research or observation. Every part of each picture is labeled, so you can connect the formulas with what you see. Developer: Fuji Bit Inc. IRAKU is the genetics edition of the "-raku" series of educational apps. It turns genetics from high school biology to introductory university courses into moving pictures, not just formulas and terms. 11 simulations in 4 categories: - DNA and gene expression - DNA Double Helix: Watch nucleotides gather, form A=T (2 hydrogen bonds) and G≡C (3 hydrogen bonds) base pairs, and wind as two antiparallel strands into a right-handed helix in 3D. Spin the finished helix with your finger. Human DNA has about 3 billion base pairs; stretched out, the DNA in one cell is about 2 m long. - Central Dogma: Using the human insulin gene, follow transcription initiation, mRNA synthesis, splicing and export from the nucleus, and translation on the ribosome. - Codon Translation: Read mRNA three bases at a time from the start codon AUG to a stop codon, with tRNAs bringing amino acids and a codon table highlighting each codon. Switch to examples of a synonymous substitution and a nonsense mutation. - How inheritance works - Mendel's Crosses: Cross round and wrinkled peas through F1 and F2. Check the 3:1 ratio (9:3:3:1 with two genes) in a Punnett square and compare it with Mendel's own counts of 5474 : 1850. - Meiosis & Crossing Over (new): Follow DNA replication, pairing of homologous chromosomes and crossing over, then meiosis I and II until four gametes form. Tell parental and recombinant gametes apart, and turn crossing over on or off. - Karyotype: Stain 46 chromosomes with G-banding and arrange them by size and centromere position into pairs 1-22 and the sex chromosomes to complete the karyotype 46,XX or 46,XY. - Populations and evolution - Mutation & Evolution: Using industrial melanism in the peppered moth, see mutation, environmental change and natural selection spread the dark form generation by generation. - Hardy-Weinberg Equilibrium: See allele frequencies p and q give genotypes p², 2pq and q², and stay the same generation after generation. Change p with a slider. - Phylogenetic Tree: Build a tree with the UPGMA method from DNA differences between humans, chimpanzees, gorillas, orangutans and gibbons. - Biotechnology - PCR Amplification (new): Watch DNA double in three steps - denaturation (95 °C), annealing (about 58 °C) and extension (72 °C) - and grow about a billion-fold in 30 cycles, with a temperature graph. - CRISPR: See a guide RNA and Cas9 find a PAM sequence (NGG), cut both strands, and the break being repaired by NHEJ (deletions and insertions) or HDR (rewriting). Switch between the two repair pathways. Features: - Clean, modern design with dark and light themes - Home screen organized by category - Every mode advances in 4 steps and ends with a real example (step back and forth with ◀ ▶ and change the speed) - Labels on every part of each picture - An explanation sheet with formulas for every simulation - In landscape, the canvas and controls sit side by side - Supports larger text sizes - Available in 73 languages, including English and Japanese (follows your device language) - No sign-in; start exploring right away Price and purchases: - Price: Free - In-app purchases: None - Subscriptions: None - Ads: Banner ads by Pangle at the bottom of the screen The "-raku" series of educational apps (selection): - SUUGAKU - Mathematics - BUTURAKU - Mechanics - DENRAKU - Electromagnetism - HARAKU - Waves - CHIRAKU - Earth Science - IRAKU - Genetics
