How is dna in a chloroplast vs dna in nucleus
Web15 apr. 2015 · By studying DNA in photosynthetic bacteria, in chloroplasts and in plant cell nuclei, biologists have shown that a key feature of the evolution of chloroplasts was the transfer of most of their original bacterial genes into the plant cell nucleus.
