Explanation
Comparing genetic material structures in cells
Steps:
- Identify key features: Eukaryotic animal cells have linear DNA in a nucleus; prokaryotes have circular dsDNA in a nucleoid without a membrane.
- Evaluate first statement: Animal cells contain linear DNA, which is true (✓).
- Evaluate second statement: Prokaryotic genetic material lacks a surrounding membrane, so false (x).
- Evaluate third statement: Prokaryotic genetic material is double-stranded DNA, which is true (✓).
Why C is correct:
- It accurately labels the statements: linear DNA in animals (true per eukaryotic definition), no membrane in prokaryotes (true, nucleoid is unbound), and dsDNA in prokaryotes (true, standard bacterial genome structure).
Why the others are wrong:
- A incorrectly marks prokaryotic membrane as true and dsDNA as true.
- B incorrectly marks prokaryotic dsDNA as false.
- D incorrectly marks animal DNA as nonlinear (false).
Final answer: C
