The Movement of Genes Between Organelle and Nuclear Genomes Is

The movement of genes between organelle and nuclear genomes is mainly supported by which of the following observations?

A) Rubisco, a multisubunit protein, consists of a polypeptide encoded by nuclear genes and a polypeptide encoded by a chloroplast gene.
B) Identical single nucleotide polymorphisms are found in both organelle and nuclear genomes.
C) Some mitochondrial proteins are encoded by genes found in the nuclear genome and some mitochondrial proteins are encoded by genes found in the mitochondrial genome.
D) RNA subunits come from both organelle and nuclear genomes that make the accompanying subunit proteins.
