A cell biologist found that two different proteins with largely different structures
were translated from two different mRNAs. These mRNAs, however, were
transcribed from the same gene in the cell nucleus. Which mechanism below
could best account for this?
O Exons from the same gene could be spliced in different ways to make different mRNAs
O The two proteins have different functions in the cell
O The gene could be transcribed in different directions
O Different systems of DNA unpacking could result in two different mRNAs
OA mutation might have altered the gene
