Chapter 1: Introduction to Cells and Cell Research (Questions 1–27)
1. RNA is believed to have been the original genetic system because it can:
,A. Store genetic information and catalyze chemical reactions
B. Form double-stranded helices
C. Replicate without enzymes
D. Only function as a messenger molecule
Answer: A. Store genetic information and catalyze chemical reactions
Rationale: RNA can both store genetic information (like DNA) and catalyze reactions (like
protein enzymes), supporting the RNA world hypothesis for the origin of life.
2. Which of the following best describes a eukaryotic cell?
A. Lacks a nucleus and organelles
B. Has a nucleus and membrane-bound organelles
C. Contains only ribosomes and DNA
D. Is always unicellular
Answer: B. Has a nucleus and membrane-bound organelles
Rationale: Eukaryotic cells possess a true nucleus and membrane-bound organelles;
prokaryotes lack these features.
3. Which laboratory technique separates cell components based on density?
A. Centrifugation
B. Western blot
C. PCR
D. Flow cytometry
Answer: A. Centrifugation
Rationale: Centrifugation separates cellular components based on their size and density
through differential sedimentation.
4. The significance of stem cells in cell research is that they:
, A. Cannot differentiate
B. Can differentiate into multiple cell types
C. Are only found in embryos
D. Have no clinical application
Answer: B. Can differentiate into multiple cell types
Rationale: Stem cells are undifferentiated cells capable of self-renewal and differentiation
into diverse specialized cell types, making them valuable for regenerative medicine.
5. Confocal microscopy provides an advantage over traditional light microscopy because it:
A. Uses electrons instead of light
B. Provides detailed 3D images of cellular structures
C. Requires no sample preparation
D. Can only view live cells
Answer: B. Provides detailed 3D images of cellular structures
Rationale: Confocal microscopy uses laser scanning and pinhole apertures to eliminate
out-of-focus light, enabling high-resolution 3D imaging of cells.
6. Which of the following is a model organism commonly used in cell biology research?
A. Homo sapiens
B. Caenorhabditis elegans
C. Pan troglodytes
D. Linaria vulgaris
Answer: B. Caenorhabditis elegans
Rationale: C. elegans is a classic model organism due to its short life cycle, transparency,
and fully sequenced genome.
7. The cell theory states that:
