BIOL 371 Lecture Notes - Lecture 2: Lophophore, Starfish, Chordate
Document Summary
Theme 1: evolutionary underpinnings of plant and animal. Cytoskeleton (cell skeleton - structure, movement, changeable) Endomembrane system systems inside the cell membrane. Primary genome of multiple, linear chromosomes regulatory dna, selective, diversity. Prokaryotes have circular dna, eukaryotes have linear dna. 80s ribosomes measure of size, differentiate between prokaryote and eukaryote. Mitochondria produce atp in this structure. Prokaryotes use cell membrane to produce atp not mitochondria. Plastids (in algae/plants) chloroplasts, some have these for photosynthesis. Sexual reproduction provides diversity through gametes and fusion of gametes, vertical transition. Microtubules hollow tube formed from tubulin dimers (protein) Microfilaments a double helix of actin monomers important for movement and shape, made of actin. Intermediate filaments strong fiber composed of intermediate filament proteins, structural size difference. Much larger with many structures inside the cell membrane bound structures. Prokaryotic cell: no membrane bound organs/ structures inside. Nucleus storehouse for cells genetic information and the site for rna synthesis.
