Homologous Shoes?

This activity, originally developed by Harry Wong, is designed to enable students to understand the difficult concept of Homology. This "concept demonstration" provides students with a concrete example (pairs of shoes in a classroom "cell") of what Homology means. It is hoped that students will use this simple demonstration to help them visualize the situation that exists in actual chromosomes. In order to be effective, students must be familiar with DNA Structure, the gene concept and the central dogma. (less)

Access to the article is free, however registration and sign-in are required: Biologists who study the fungus Candida albicans have always assumed that this organism reproduces asexually because they have not found evidence of mating, meiosis, or a haploid stage of the life cycle. However, as Gow et al. explain in a Perspective, sequencing of the C. albicans genome has revealed the existence of a possible mating type locus. This finding has now been extended to demonstrate actual mating in the fungus (Hull et al., Magee and Magee). (less)
