a haploid fungus, a transversion arises in the coding region of a gene necessary for the production of the amino acid leucine. The transversion substitutes the last base in the codon UAC (encoding cysteine), resulting in the stop codon UAG. This substitution will most likely cause;

The correct answer is - the production of a truncated (shortened) protein.

Explanation:

In this question, it is given that there is a transversion type of substitute mutation that causes the change in the coding region of a gene. By this transversion, there is a substitute in the last base of the UAC code of gene that codes for leucine amino acid to a stop codon.

As stop codon comes before the actual stop codon in the gene leads to terminate the translation of mRNA to the amino acid chain that results in shortened or truncated protein.

answer: that would be cheating
