Mutations test question suggestion
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.

The diagram shows a portion of the genetic code. The diagram is read from the center of the circle outwards. So, the codon AGU is translated as serine, which is an amino acid.
Which conclusion about the genetic code is most strongly supported by the evidence presented in the diagram?

Many codons, although not all of them, may be translated into two or more amino acids.

Many amino acids, although not all of them, may be encoded by more than one codon.

Every codon may be translated into two or more amino acids.

All amino acids may be encoded by more than one codon.
