3. CCoding sections joined together to form the mature mRNA
4. DCodons that tell the ribosome to stop translation

A leaf with green and white areas is kept in light and then tested with iodine. Only the green areas turn blue-black. What does this show?

1. AWhite areas store more starch than green areas
2. BLight is not needed for photosynthesis
3. CChlorophyll is needed for photosynthesis
