Document Summary

Cycle 1 outcomes: trapping light for energy and. Lecture 1: characteristics of chlamydomonas that make it a useful model system. Generation to generation time is relatively quick, making mutations/adaptations quicker to occur and monitor. Fundamental eukaryotic characteristics and processes: relatedness of chlamydomonas to plants and animals. Chlamydomonas relatedness to plants: chlamydomonas are considered green algae, diverge from plants relatively quickly on phylogenetic trees, plants and chlamydomonas are both photosynthetic (producing their energy using light), both have channelrhodopsin. Chlamydomonas relatedness to humans: both eukaryotic, have similarities in flagella structure, eyespot and eyes have similarities in terms of phototaxis, animals have rhodopsin whereas chlamydomonas has channelrhodopsin, relationship between genome size and protein coding genes. Genomes size is not indicative of the number of protein coding genes: genome size increases as the organism becomes more complex. Chlamy has 120 mb and h. sapiens have 3,000 mb. Chlamy has 15,000 and h. sapiens have 20,000.
