give you an answer?
a. you explore whether there has been alternative splicing by examining amino acid
sequences of very similar proteins.
b. you measure the quantity of the appropriate pre-mrna in various cell types and
find they are all the same.
c. you assess the position and sequence of the promoter and enhancer for this gene.
d. an analysis of amino acid production by the cell shows you that there is an increase at
this stage of embryonic life.
e. you use an antibiotic known to prevent translation.
