BIOMG 1350 – Section 9 Homework and Worksheet 1 Name: Section: Model Organisms: Use the pages in your textbook on model organisms (ECB, pp. 26-33), the literature “Model organisms — A historical perspective” (on Blackboard), and the internet to fill in the information about just your assigned model organism. Yeast (Saccharomyces cerevisiae) Plant (Arabidopsis thaliana) Roundworm (Caenorhabditis elegans) Fruit fly (Drosophila melanogaster) Zebrafish (Danio rerio) Mouse (Mus musculus) Organism size Rearing conditions Generation time Life span Genome size (# of nucleotide pairs and number of genes) Advantages & disadvantages to using this particular model organism Alexandra AltamiranoAdvantages: small vertebrate, mouse is a mammal so good model for humans, have embryonic stem cells, quick reproduction rates Disadvantages: poor accessibility as embryo develops inside womb, small batches of embryos-10 per litter, expensive to keep in a labtissues are 36-38 celcius in culture media. cared for until 21 days. 5-10 litters per year w/ 3-10 offspring per litter2800 X 10^6 base pairs7.5-10 cmmales: 50 days females: 50-60 days1.5-3 years~30,000 genesBIOMG 1350 – Section 9 Homework and Worksheet 2 Note: Online databases are available for each model organism. Through these databases you can access sequence information, gene expression information, mutants and transgenic lines, publications, rearing techniques, etc. 1.
