1. Multiple Choice
Question : Which of the following is the primary function of
mitochondria in eukaryotic cells?
a) Protein synthesis
b) Energy production
c) DNA replication
d) Cellular signaling
ANS : b) Energy production
©2025
, Rationale : Mitochondria are known as the "powerhouses" of
the cell, where cellular respiration produces ATP for energy.

2. Fill-in-the-Blank
Question : The process by which DNA is copied into mRNA is
called __________.
ANS : Transcription
Rationale : During transcription, a segment of DNA serves as a
template for the synthesis of messenger RNA.
---
3. True/False
Question : Prokaryotic cells lack membrane-bound organelles,
including a nucleus.
ANS : True
Rationale : Prokaryotes, such as bacteria, do not have
membrane-bound organelles; their genetic material is located in
the nucleoid.

4. Multiple Response
Question : Which of the following are macromolecules essential
to life?
a) Proteins
b) Lipids
c) Carbohydrates
d) Vitamins
ANSs : a) Proteins, b) Lipids, c) Carbohydrates
Rationale : Proteins, lipids, and carbohydrates are essential
biological macromolecules, while vitamins are micronutrients.

5. Multiple Choice
Question : In the context of genetics, what is an allele?
a) A type of mutation
b) An alternate form of a gene
c) A protein coding sequence
©2025
, d) A structural component of DNA
ANS : b) An alternate form of a gene
Rationale : Alleles are different versions of the same gene that
can produce variations in a trait.
---
6. Fill-in-the-Blank
Question : The process of cell division that results in two
identical daughter cells is called __________.
ANS : Mitosis
Rationale : Mitosis ensures that each daughter cell receives an
exact copy of the parent cell’s genetic material.
---
7. True/False
Question : Enzymes lower the activation energy of chemical
reactions, increasing the reaction rate.
ANS : True
