Document Summary
Lecture: relative sizes of typical mitochondrial, chloroplast and nuclear genomes, nuclear genome (linear) > chloroplasts genome (circular) > mitochondrial genome (circular) Multiple genes could code for one protein. Nucleus already has genes so you don"t need them in mitochondria. Genes code for things other than proteins (ie. ribosomes) all genes get transcribed into rna but the function of that. Rna could be very different (trna, mrna) Some genes code for rna and rna is the functional product genome to e. coli. Certain genes have been deleted. Coordinated control between the nucleus and the organelles oxygen species (oxygen +electron=reactive oxygen species). Dna away rom the ros"s this is an alternative hypothesis for lateral gene transfer. Sometime gene products need to be produced locally turnover) Something in the pathway to the nucleus may break the genes down. Initial end of the rna transcript is 5" and the other end is 3".
