Post-Transcriptional Processing

APBIO-V12YEY

Which of the following BEST describes how the mRNA undergoes a series of modifications after transcription?

A

A GTP cap and a poly A tail are added to protect the mRNA as it leaves the nucleus.

B

Splicing of the tRNA occurs to remove excess portions that will not be expressed during translation.

C

Exons are spliced out from the mRNA and introns are spliced together to make a final mRNA transcript.

D

Post-transcriptional editing of RNA is performed in both prokaryotes and eukaryotes depending on the gene that is being transcribed.
