Question

Sometimes knowing the DNA sequence of a gene that codes for a protein does not tell one the amino acid sequence of the mature protein. What is/are reason) s) for this? (Select all that apply.) Splicing of mRNA may alter the RNA transcript prior to protein translation. Some mature proteins have a portion of their pro-protein sequence removed. Not all protein translation processes have complete fidelity to the gene sequence. Some DNA samples are difficult to sequence, thus leading to errors in the gene sequence.

Explanation / Answer

The correct answer is :Splicing of mRNA may alter the RNA transcript prior to protein translation.

Reason: Not all the DNA sequences transcribed to mRNA are translated to aminoacids in proteins.Prior to translation the mRNA undergoes spilcing to remove non coding genes known as introns.
