MCB 410 Exam 1 Lecture UPDATED ACTUAL Questions and
CORRECT Answers
Your friend works in a biotechnology company and has Nuclear transport receptors would be unable to release their cargo in the nucleus
discovered a drug that blocks the ability of Ran to
exchange GDP for GTP. What is the most likely effect of
this drug on nuclear transport?
Which of the following statements about vesicular The GTP hydrolysis of the Rab proteins provides the energy for membrane fusion.
membrane fusion is FALSE?
Which of the following statements about membrane- In a typical cell, the area of the endoplasmic reticulum membrane far exceeds the
enclosed organelles is TRUE? area of plasma membrane.
The γ-tubulin ring complex is to microtubules what ___ is the Arp 2/3 complex
to actin filaments.
Active transport requires the input of energy into a K+ -coupled
system to move solutes against their electrochemical and
concentration gradients. Which of the following is NOT
one of the common ways to perform active transport?
Given what you know about the differences between DNA replication
prokaryotic cells, and eukaryotic cells which of the
following biological processes is suitable for study using
E. coli as the model organism?
The bond energies associated with noncovalent Many weak bonds together in a complementary geometry can afford a strong
attractions in the cell are too weak to resist disruption by binding.
thermal motion. However, cellular macromolecules can
interact specifically AND strongly with each other (or fold
by themselves) merely via such interactions. How is this
possible?
Which of the following statements about gap junctions is Because gap junctions only allow uncharged molecules to pass through, they are
FALSE? not used for electrically coupling cells.
What unit of length would you generally use to measure micrometers
a typical plant or animal cell?
Which of the following statements is TRUE? Membrane lipids diffuse within the plane of the membrane.
Tight junctions are formed from claudins and occludins.
