Answer:

A buildup of sticky mucus on the outside of the cell

Step-by-step explanation:

The deletion of the codon means that the protein the gene codes for is missing one amino acid.

That protein acts as a Cl⁻ channel in the cellular membrane and controls the movement of water in the tissues.

The water produces thin, freely flowing mucus. Without the water, a coating of thick mucus builds up on the outside of the cell.
