Increase the amount of neurotransmitter (ligand) released
Decrease the voltage requirement for voltage-gated Na+ channels
to open
Increase the number of ligand-gated channels at the membrane
All of the above
None of the above
If the template strand of DNA for a small piece of RNA is
5’-CCAGTAGAG-3’, then the mutation 5’-CCAGTAGGG-3’ won’t
change the amino acids translated from that piece of RNA.
True
False
“X”, a large polar molecule, needs to be transported inside of
the cell. It has a steep gradient across the membrane
(outside>> inside) and has a dedicated transporter at the
membrane. Despite these parameters, you observe a low rate of
transport inside of the cell for “X”. Which of the following
statements may help explain this?
The transporter has a low Km for “X”
The transporter has a high Km for “X”
None of the above
The transporter requires ATP for the transport of “X”
Which of the following would you expect to only find
in a euchromatin region?
Methylated lysines in the histone tails
TATA boxes
Transcription factors
Methylated CpG islands
Mutagenic agents mainly work by:
Disrupting the hydrogen bonding capabilities of nucleotides
None of the above
Disrupting the phosphodiester bond between nucleotides
Disrupting the deoxyribose and base bond
