Describe how the mutation has affected the protein coded by this gene

answer:

since the sequence of letters in a gene determines the sequence of amino acids in the protein it encodes, a point mutation can change the amino acid sequence of the resulting protein.

sometimes a change in the protein's amino acid sequence can have dramatic results.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
