All corn plants contain the ZmLA1 gene. Some corn plants contain a certain mutation in the ZmLA1 gene. The graph below shows the amount of ZmLA1 RNA produced in plants with the normal gene and in plants with the mutated gene.
Based on the graph, what most likely happens in corn plant cells as a direct result of the mutated gene?
DNA replication increases.
Lipid production decreases
Glucose synthesis increases.
Protein production decreases.
