The paper describes an interactive computer program for visualizing bacterial gene regulation: the trp operon. The computer program was implemented based on our recently developed Gene Act framework. The advantages of this computer framework are 1) accelerating the development process and 2) simplifying the program development for researchers who wish to pack and distribute their work with interactive...
Genetic recombination is an important process for DNA repairing and increasing genetic variation, thereby enriching the gene pools for the survival and vitality of a species. In eukaryotes, meiosis is a major means for genetic recombination. For genes on non-homologous chromosomes, mixing of paternal and maternal genes is achieved through different chromosome configurations at metaphase I of meiosis...
The G-banding technique is routinely used for generating characteristic banding patterns for chromosome identification and karyotyping. Since G-band patterns are not static, training cytogenetics technologists to master the skills of chromosome analysis is a long process. Furthermore, the opportunities for biology students to access a wide range of different chromosome aberrations for practice are...
Teaching fundamental principles of genetics such as segregation and independent assortment of genes could be challenging for high school and college biology instructors. Students without thorough knowledge in meiosis often end up of frustration and failure in genetics courses. Although all textbooks and laboratory manuals have excellent graphic demonstrations and photographs of meiotic process, students...
