Document Summary
Genome structure: single compartment in bac, archaea, virus, 3 compartments in euk (nuclei, mito, chloroplast) There are species that have lost mitchon genomes (rare: land plants-3 components (nucleus, mitcho, chloroplast) Still there are its still performing some crucial function (which is why its maintained. Function is nuclear encoded proteins (coded by nucleus and transfer to organelles) Nucleomorph (rare: mitcho/nucleus goes away and whats left is 2 chloroplast (membrane) Some organisms have partial nucleus remaining (additional genome that present) Due to progress of merging is still in progress (rare) 2 chloroplast is rare therefore to catch the time of process is just as rare. Genome structure variation: size, content: how many/dense, structure: shape of genome takes. # pieces: can be broken in several pieces. Chromosomes varies a lot w/species why? no answer, must be a process that happens to cause them persist that way.
