A Eukaryotic Gene Is Observed to Make Multiple Forms of a Protein.How

question 31

Multiple Choice

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.
