Jaffe BIO 1404 Exam 6 -Questions and Answers
Using the table above, determine the peptide sequence for the following sequence of mRNA
codons: '3-AUG-ACU-CCG-GUA-5' Correct Ans-Met-Ala-Ser-Val
An X chromosome that is inactivated would most likely exhibit Correct Ans-less gene
expression
In an inducable operon, such as the lac operon Correct Ans-gene expression is facilitated
by the presence of a co-factor
For the lac operon, in the absence of lactose, the repressor protein Correct Ans-blocks RNA
polymerase from reaching the protein-coding region
Protein synthesis begins with the formation of initiation complex, composed of which of the
folowing Correct Ans-mRNA, small ribosomal subunit, initiator DNA
DNA polymerase III is responsible for Correct Ans-adding new DNA nucleotides to a 3'

, Jaffe BIO 1404 Exam 6 -Questions and Answers
You have discovered an enzyme that when activated increases the number of adenines added
to the 3' tail of mRNA for hemoglobin in bone marrow cells. This will have the effect of
Correct Ans-increasing the overall amount of hemoglobin
A protein that has many ubiquitin molecules attached to it will be degraded by the Correct
Ans-proteasome
Which of the following is a coding region of DNA Correct Ans-exon
Simultaneous transcription and translation can occur in Correct Ans-prokaryotic cells
To perform gel electrophoresis, a sample of DNA is placed between two electrodes. DNA is
attracted to the positively charged electrode. This is because DNA Correct Ans-is rich in
phosphate groups
