Document Summary

Building & maintaining a living system: information: store (instructions, copy (inherit, process, regulate flow, intracellular, extracellular. Chromosomes: physical entities that constitute a genome: many people use the two terms interchangeably (usually not an issue) Genome sequence organization for bacteria & eukaryotes: gene sequences vs. non-genic sequences: embedded information (actg base pairs) for gene, regulation & timing organization of genes within a genome, bacteria: non-genic. <10% non-genic or intergenic average sign = size. 10000 20000: bacteria/archaea: beginning: 5" end repetitive sequences/transposons: end at the 3" end not all the genes go the same way interomigration unique sequences = clusters by function (aperons) 1 32% repetitive sequences transposons embedded information (actg base pairs) for genes regulation & timing scattered directional with 3" & 5" ends: eukaryotes: >10% non-genic average genes: 10,000 100,000 bp directional (3 3" prime end), either scattered / not clustered: repetitive sequences: tandem or satellite repeat. 10 -100,000 copies of each: most of genome not composed of genes.
