Document Summary

Cycle 7 - organelle genes and lateral gene transfer. Lateral gene transfer does happen from the chloroplast to the nucleus: but we are focusing on lateral gene transfer that occurs from the. Purpose is to move genes from the mitochondria to the nucleus permanently: products go to them mitochondria and chloroplast to work but not the genes. A : oxphos subunits: complex i, ii, iii, iv and atp synthase and they all need to be maintained, complex i has 45 proteins, about 37 are encoded in the nucleus the remained encoded in the mitochondria. Many proteins have to be synthesized outside of the mitochondria and then translocated back into the mitochondria. B: mitochondrial dna maintenance/expression: a lot of processes/proteins have to come together to maintain the dna, dna replicates in the mitochondria, has multiple copies of dna within the mitochondria.
