Molecular Biology Fundamentals Test Exam
Questions And Answers Verified 100% Correct
Chaperonin - ANSWER -Protein molecules that assist in the
proper folding of other proteins
Enzymes composition - ANSWER -Mostly made of proteins
DNA and RNA - ANSWER -Polymers responsible for genetic
information storage and transmission
Flow of genetic information - ANSWER -DNA to RNA to
Protein
Lipid classification - ANSWER -Grouped due to hydrophobic
nature despite structural differences
Fatty acids and phospholipids structure - ANSWER
Hydrocarbon chains with carboxyl group; phospholipids
have hydrophilic head and hydrophobic tail
Saturated fats - ANSWER -Single bonded carbon atoms with
maximum hydrogen atoms
, Unsaturated fats - ANSWER -Double bonded carbon atoms
with fewer hydrogen atoms
Plasma membrane structure - ANSWER -Phospholipid bilayer
with embedded proteins and carbohydrates
Receptors on plasma membrane - ANSWER -Composed of
glycoproteins
Molecules passing through plasma membrane - ANSWER -
Small and non-polar molecules pass more easily
Osmosis - ANSWER -Passive movement of water through a
selectively permeable membrane
Active transport - ANSWER -Movement of molecules across a
membrane requiring energy
Sodium potassium pump - ANSWER -Example of active
transport
Osmosis consequences - ANSWER -Cell shrinkage in
hypertonic solution, cell swelling in hypotonic solution
Bulk transport - ANSWER -Transport of large molecules in
and out of the cell via vesicles
