Document Summary
Characteristics of chlamydomonas that make it a useful model system: uses light for 2 very different reasons. Light as an energy source --> making atp (like plants it is photosynthetic. -> eyes: has flagella like eukaryotes but also has chloroplasts --> diverged from plants. Used to research diseases --> many human diseases caused by flagella. 2. or cilia defects: genome is completely sequenced --> can be compared to its relative multicellular organisms by genome! Turns out genomes of chlamy and multicellular algae = very similar -> 1. how did multi-cellularity arise then: very easy to make mutations in chlamy also! Relatedness of chlamydomonas to plants and animals: diverged from land plants about 1 billion years ago --> mcra with plants and algae 1 bil yrs ago, has flagella (eukaryotic trait) and chloroplasts (plant trait) Relationship between genome size and protein coding genes: protein coding gene (pcg) of chlamy 15,000 pcg / 120mb genome, h. sapiens = 20,000 pcg / 3000mb.
