Question

review the passage about the effects of the cmaco1 gene mutation.
in plants such as the european cantaloupe, fruit ripening is affected by a substance called ethylene (eth-uh-leen). ethylene is made inside a plant’s cells with the help of a protein called cmaco1. the cmaco1 protein is encoded by the cmaco1 gene.
a certain european cantaloupe plant had a mutation in its cmaco1 gene. compared to the cmaco1 gene without a mutation, the mutated cmaco1 gene encoded a form of the cmaco1 protein with a different structure.
this different form of the cmaco1 protein could make only a small amount of ethylene. the fruits of this plant took longer to ripen than fruits from plants containing more ethylene. farmers found this mutation useful because the fruit stayed good for a longer period of time after harvest.
fill in the blanks.
a cantaloupe plant trait the cmaco1 gene the cmaco1 protein
the mutation in affected the structure and function of
in a way that affected .

Explanation:

The passage states that the mutation is in the CmACO1 gene. This mutation affects the structure of the CmACO1 protein (as the gene encodes the protein). The change in the protein's structure then affects its function (it makes less ethylene). The reduction in ethylene production affects the fruit - ripening trait (as ethylene is involved in fruit ripening).

Answer:

The mutation in the CmACO1 gene affected the structure and function of the CmACO1 protein in a way that affected a cantaloupe plant trait.
