In a Haploid Fungus,a Transversion Arises in the Coding Region

Multiple Choice

In 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:

A) the production of a truncated (shortened) protein.
B) the production of a truncated (shortened) mRNA.
C) the production of a shortened mRNA and of a shortened protein.
D) no detectable phenotype.
E) inability to grow on medium that lacks cysteine.
