Question

Indicate whether eac is true for gene expression in prokaryotes,eukaryotes or both:

1. After transcription, a 3' poly- A tail and a 5' cap areaddeddto the RNA.

2. Translation of mRNA can begin before transcription iscomplete.

3. RNA polymerase binds to the promoter region to begintranscription

4. RNA polymerase can only add a robonucleotide to the 3' end ofthe growing RNA

5. The mRNA transcript is the exact complement of the gene fromwhich it was copied.
