Transcription and mRNA Processing Practice Quiz
1. Transcription , while translation .
a. Requires ribosomes; requires tRNAs and RNA polymerase
b. Occurs in cytosol of eukaryotic cells; occurs in the nucleus of eukaryotic cells
c. Is the synthesis or RNA; is the synthesis of protein
d. Requires tRNA; requires rRNA
2. Put the rolling steps of transcription in the correct order
i. RNA polymerase binds the promoter
ii. RNA polymerase reaches the terminator
iii. Transcription bubble formed
iv. RNA polymerase makes RNA, beginning at the start point
a. 1-3-4-2
b. 1-4-3-2
c. 4-1-3-2
d. 3-1-4-2
3. Which of the following is accurate for BOTH DNA polymerase and RNA polymerase
a. They both make RNA
b. They both unwind the double helix
c. They both work in the nucleus and build molecules in the 5’ to 3’ direction
d. They both need primers or some other existing strand with a 3’-OH to function
e. They both make DNA
4. Match the RNA with its description/function
a. mRNA -- carries a genetic message from the DNA to ribosomes
b. rRNA -- along with proteins, is part of the structure of ribosomal subunits
c. tRNA -- transfers amino acids from a cytoplasmic pool of amino acids to
a growing polypeptide in a ribosome
d. snRNA -- matches specific sequences in introns; required for splicing
