Document Summary

1. 3: characteristics that distinguish eukaryotic and prokaryotic cells. Genetic info is encoded in dna using identical genetic code (atcg)division. Similar mechanisms for transcription and translation of genetic code. Similar equipment for conserving chemical energy as atp. Similar mechanism of photosynthesis (between cyanobacteria and green plants) Similar mechanism for synthesizing and inserting membrane proteins. Proteasomes (protein digesting structures) of similar construction (between archaebacterial and eukaryotes) Cytoskeleton filaments built of proteins similar to actin and tubulin. Division of cell into nucleus and cytoplasm. The nucleus is separated by a nuclear envelope that contain pore structures. Complex chromosomes composed of dna and associated proteins. Golgi apparatus (materials are sorted, modified, transported to specific destinations) Cytoskeletal system: (involved in movement and support) Phagocytosis= ability to ingest material by enclosing material within plasma membrane vesicles. Cell division with the help of spindle fibres that help separate chromosomes during mitosis. Presence of two copies of a gene per cell (one from each parent)
