BCH403 PRACTICE TEST QUESTIONS
WITH CERTIFIED ANSWERS
E6: Which one of the following mRNA sequences contain an arginine residue as the 4th
amino acid in reading frame 3? A codon table is located on the last page of this exam
booklet. - Answer-5' UUUGACCGACCAGAACCC 3'
E6: Which one of the following is not involved in translation initiation prokaryotes? -
Answer-Methionyl-tRNA
E6: Which of the following post-translational modifications is most common in humans?
- Answer-Phosphorylation
E5: Which one of the following correctly describes the termination prokaryotic DNA
replication? - Answer-An asymmetrical protein-DNA complex stalls the first replisome to
reach the termination signal. The second replisome will collide with the stalled
replisome, knocking both replisomes off the template.
E5: Which one of the following is complexed with a kinase and is partially responsible
for regulating the cell in eukaryotes? - Answer-Cyclin D
E5: Which one of the following is never involved in DNA homologous recombination? -
Answer-Non-homologous end joining (NHEJ)
E5: Factor-independent transcriptional termination: - Answer-Occurs when the RNA
polymerase reads and writes a symmetrical GC-rich region followed by an A-rich region.
E5: Which one the following is not required for transcription initiation in humans? -
Answer-Nucleotide triphosphates
E5: Which one of the following is not a potential function of histone methylation? -
Answer-Promote euchromatin formation by decreasing the charge of histone.
E5: During transcription, the RNA polymerase reads the of
DNA. - Answer-Anti-sense strand
E5: Which one of the following is true regarding epigenetic modifications? - Answer-
They can be influenced by the environment.
E6: The 5' and 3' ends of tRNA are cleaved during processing. - Answer-TRUE
E6: DNA damage always results in mutation. - Answer-FALSE
E6: Prokaryotic mRNA is circularized during translational initiation. - Answer-FALSE
E6: Post-translational modifications may help a protein fold correctly. - Answer-TRUE
E6: Molecular testing is used to measure protein activity or protein levels to help
diagnose a disease. - Answer-FALSE
, E6: The protein complex that adds the poly A tail to be 3' of mRNA is also involved in
termination of transcription. - Answer-TRUE
E6: Non-Watson and crick base pairing can occur between the anti-codon in the codon.
- Answer-TRUE
E6: tRNAs recognize stop codons, which signal the termination of translation. - Answer-
FALSE
E6: Free ribosomes translate proteins targets the nucleus. - Answer-TRUE
E6: DNA sequencing alone cannot be used to study the epigenome. - Answer-TRUE
E6: Which one of the following protein catalyzes the 5' ---> 5' bond when adding the 5'
cap to mRNA? - Answer-RNA guanylyltransferase
