a bacteriologist induces a mutation in a gene for a 100 amino acid protein. upon further analysis, it was found that when the mutant gene is expressed, a 50 amino acid mutant protein is made. the mutant protein consists of the first 50 amino acids of the wild type protein. This mutant could be the result of... a. a single base pair mutation b. a deletion of one nucleotide c. an insertion of one nucleotide d. a deletion of 4 nucleotides e. all of the above

Step 1
A single base pair mutation could change a codon to a stop codon, which would terminate the translation of the protein. However, this is unlikely to happen exactly at the 50th amino acid position, so this option is not the most probable. Show more…

A geneticist found that a particular mutation had no effect on the polypeptide encoded by a gene. This mutation probably involved a. deletion of one nucleotide. b. alteration of the start codon. c. insertion of one nucleotide. d. substitution of one nucleotide.
