Document Summary
Clone orf, put into another host, see if it make a protein. Can you ind it in another organism o o o o o. If you are conident the genes you found are real . Blue and orange circle refers to the botom picture. Genes can be coded on either strand o o. Where exactly are genes in the dna? o. Some on one, some on the other strand. Tightly packed genes because in prokaryotes, less iller dna. The above genes are bigger than prokaryoic genes. Most of you genes are intron region - take up vast majority of coding region. Prokaryotes have a kind of intron: very diferent from eukaryoic introns that we don"t call them introns o. Maybe these prokaryoic sequences are origin of eukaryoic introns. Somewhere on the branch to eukaryotes, introns became widespread o. Maybe irst organism taken up, and became mitochondria o. Nucleus became infected with mobile sequences, during lgt.
