Each of the mutants listed below this paragraph has a different
mutant form of the gene encoding protein X. Each mutant gene
contains one or more nucleotide insertions (+) or deletions (−) of
the type caused by acridine dyes. Assume that all the mutations are
located very near the beginning of the gene for protein X. In each
case, indicate with an “OK” if you would expect the mutant protein
to be nearly normal and with a “Not OK” if you would expect it to
be obviously abnormal.
