A eukaryotic gene is observed to make multiple forms of a protein.How can one eukaryotic gene produce multiple products in the same cell?
A)Alternative splicing sites can lead to the production of two different mature mRNAs from the same gene,resulting in slightly different proteins.
B)Epigenetic changes can change the sequence of amino acids in a protein.
C)Translation rates can affect the length of the polypeptide made from the same mRNA.
D)Silencer genetic elements can cause early termination of transcription,leading to the production of multiple mature mRNAs from the same gene.
E)One gene equals one protein,so this observation must be incorrect.
