Document Summary
Differences in genome architecture and the forces responsible for differences when we talk about genome evolution: size, structure. Differences in structure like circular, linear, fragmented: content. Genome architecture encompasses the content: stretches of at rich or gc rich dna. Are there many genes that are tightly packed or are there long stretches of dna. Is it being processed: maybe it is being translated in the nonstandard code. All of these things are a part of genome architecture: huge diversity in genome architecture, within cells, lineages and between different lineages. A lot of the differences in the tree of life and you find diversity within a single cell if you compare the organelle and nuclear genomes. You need to think about it on a molecular level and also the population level. Molecular level: the only way to get different genome architecture (diversity) is through mutations.
