The purpose of this study is to analyze how the molecular mechanisms of animal development have been described through curriculum analysis and to suggest appropriate ways to understand the regulation of gene expression during animal development in the new curriculum. Studies on the development of animals have developed rapidly around the 1980s with the discovery of genes from fruit flies. Pattern formation occurs stepwise through differential expression of the gene. For the first time in Korean 2009 revision curriculum, animal evelopment and regulation of gene expressionhave been discussed in the biology curriculum together. The 2015 revision curriculum also covers development and regulation of gene expression using the homoeotic genes as an example. The core function of the homeotic genes are to provide the positional information along the anterior to posterior axis so that the structure is formed at the appropriate location. Antennapedia (Antp) and Ultrabithorax (Ubx) mutants were first found in the fruit fly, and the two mutant phenotypes are very distinct and easily observed. In addition, the nucleotide sequences of two genes were compared, which showed a conserved base sequence called homeobox, with which many homologous genes were found in other animals. Therefore, it is very important to understand the phenomena common to species through the mutation of homoeopathic genes among animals, and it is also necessary to examine them from an evolutionary point of view. |
