Where are the Molecules Used to Carry Out Photosynthesis Encoded

Question

Where are the molecules used to carry out photosynthesis encoded?
A)All are encoded in chloroplast DNA.
B)Some are encoded in chloroplast DNA and others in nuclear DNA.
C)All are encoded in nuclear DNA.
D)Some are encoded in nuclear DNA and others in mitochondrial DNA.

Accepted Answer

Photosynthesis involves proteins and enzymes encoded by genes located in both the chloroplast DNA and the nuclear DNA. Chloroplasts have their own genome, which encodes some of the necessary components, but many essential proteins are encoded by nuclear genes and then imported into the chloroplast.
