BIOL 102 Lecture Notes - Lecture 13: Dna Replication, Prokaryote, Cell Membrane
Document Summary
Photosynthetic organisms capture light energy transform it into chemical energy. Photoautotrophs ~fixing co2 building own food from carbon dioxide. Heterotrophs ~ getting carbon from organic compounds they break down. Mitochondria are not shared among prokaryotes and eukaryotic. Dna is transcribed into rna rna is translated in proteins (both have ribosomes, trna) Dna is the hereditary material (replicated, transcribed into rna) Common set of metabolic pathways (e. g. glycolysis ***) Are unicellular but can form large coordinated colonies or biofilms or filaments. Most cases, chromosomes are circular (eukaryotes have linear chromosomes) Divide by binary fission (eukaryotes divide by mitosis) Lack membrane bound organelles but can have infoldings of the plasma membrane or cell membrane or internal membranes (e. g. thylakoids) Doesn"t have internal organelles that are membrane bound. Enter into the cell and integrate into the genome. Plasmids being exchanged btw different strains of bacteria. Conjugation - dna can be replicated and exchanged to a bacterial host ***
