A Levels Biology (9700)•9700/11/O/N/23
Question 6 from 9700/11/O/N/23

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

Topic: Cells as the basic units of living organisms
