MOLECULAR BIOLOGY OF THE CELL 7TH
EDITION EXAMINATION TEST 2026 FULL
QUESTIONS AND ACCURATE SOLUTIONS
GRADED A+
⩥ What are the universal determinants of life? Answer: Heredity,
Metabolism, Compartmentalization.
⩥ What is the role of DNA in living cells? Answer: DNA stores the
appropriate biological information for life.
⩥ What process do all cells use to transcribe DNA? Answer: All cells
transcribe portions of their DNA into RNA.
⩥ What is the Central Dogma of molecular biology? Answer: It dictates
how DNA is read and translated into proteins.
⩥ What is templated polymerization? Answer: The process through
which all cells replicate their hereditary information.
⩥ How do cells maintain their organization? Answer: Through
metabolism, which allows them to consume energy.
, ⩥ What is homeostasis in the context of cellular metabolism? Answer:
Cells are in a state of trying to attain a non-entropic energy balance.
⩥ What is the significance of DMS (di-methylsulfide) in the search for
extraterrestrial life? Answer: It was considered a biosignature indicative
of metabolism.
⩥ What is the smallest known living organism? Answer: Mycoplasma
genitalium.
⩥ How many genes does Mycoplasma genitalium have? Answer: It has
a genome of only 525 genes.
⩥ What is the primary function of compartmentalization in cells?
Answer: To contain biochemical factories within an enclosed plasma
membrane.
⩥ What is the importance of protein or RNA catalysts in cellular
metabolism? Answer: They ensure biochemical reactions occur
efficiently.
⩥ What must all cells do to replicate their genomic information?
Answer: They must faithfully replicate it and pass it along
independently.
