Suppose a mutation occurred that prevented a eukaryotic pre-mRNA from receiving a 5ʹ cap. What would be an expected result?
A) Transcription would continue past the end of the gene coding sequence resulting in a longer pre-mRNA transcript.
B) Translation would continue past the end of the gene coding sequence resulting in a longer pre-mRNA transcript.
C) Transcription would not occur as the transcription factors would not be able to bind to the promoter.
D) Translation would not occur as the ribosome would not be able to bind to the mRNA.
E) Replication would not occur as DNA polymerase would not be able to bind to the DNA at the origin of replication.

The 5' cap is crucial for the ribosome to recognize and bind to the mRNA for translation initiation. Without the 5' cap, translation would not occur.
