Document Summary
All cells: store data as dna, use rna as intermediary form of data, use proteins as catalysts, translate rna the same way (via ribosome, are enclosed in a plasma membrane. Homologous genes genes that were once the same gene (but was changed: orthologs. same gene diverged due to intragentic mutations into 2 different genes. duplication and divergence of genes in the same organism. Gene transfer between organisms: bacteriophage viruses can implant dna into bacterial genomes, procaryotes can take up random dna from environment. Model organisms (m. o. : rapid development, tractability, small adult (mature stage, readily available, genes understandable. e. coli: used to model prokaryotes and bacteria, lives in your gut. arabidopsis: m. o. for plants, the common thale cress. caenorhbditis elegans: nematode worm, has exactly 959 body cells. Eukaryotes: entered endosymbiosis with a small energy generating bacteria (later the mitochondria, some cells then formed symbiosis with a chloroplast-like bacteria.
