The molecules used in a chloroplast to carry out photosynthesis:
A) are all encoded by chloroplast DNA.
B) some are encoded by chloroplast DNA,others by nuclear DNA.
C) are all encoded by nuclear DNA.
D) some are encoded in nuclear DNA and some in mitochondrial DNA.
E) some are encoded in chloroplast DNA and some in mitochondrial DNA.

Question

Quizplus · Accepted Answer

Chloroplasts have their own DNA, but not all of the molecules used in photosynthesis are encoded by chloroplast DNA. Some molecules, such as those involved in energy conversion, are encoded by nuclear DNA. Therefore, some molecules are encoded by chloroplast DNA and others by nuclear DNA.
