Sample Questions and Answers for Biology 7401/1 Paper 1

To provide a practical understanding of the types of questions that may appear in the Biology 7401/1 Paper 1, here are some sample questions along with detailed answers:

Question 1: Multiple Choice Question

Which of the following organelles is responsible for protein synthesis?

a) Mitochondrion

b) Chloroplast

c) Ribosome

d) Golgi apparatus

Answer: c) Ribosome

Explanation: Ribosomes are the sites of protein synthesis in the cell. They are responsible for translating mRNA into proteins.

Question 2: Short Answer Question

Define the term "osmosis."

Answer: Osmosis is the movement of water molecules from a region of higher water potential to a region of lower water potential through a semi-permeable membrane.

Question 3: Structured Question

Explain the process of DNA replication in detail.

Answer: DNA replication is the process by which a DNA molecule is duplicated. The process involves the following steps:

1. Initiation: Replication begins at specific sites called origins of replication. Enzymes called helicases unwind the DNA double helix, creating a replication fork.
2. Elongation: DNA polymerase enzymes add nucleotides to the 3' end of the template strand, synthesizing a new DNA strand complementary to the template. One strand is synthesized continuously (leading strand), while the other is synthesized in short fragments (lagging strand).
3. Termination: Replication continues until the entire DNA molecule is duplicated. The fragments on the lagging strand are joined together by DNA ligase.
4. Proofreading: DNA polymerase also has a proofreading function, correcting any errors that may occur during replication.

Question 4: Data Analysis Question

The graph below shows the rate of photosynthesis at different light intensities.

[Insert a graph showing photosynthesis rate vs. light intensity]

What conclusion can you draw from the graph?

Answer: The graph shows that the rate of photosynthesis increases with increasing light intensity, up to a certain point. Beyond this point, the rate of photosynthesis plateaus, indicating that light intensity is no longer the limiting factor.

Question 5: Essay Question

Discuss the role of natural selection in the process of evolution.

Answer: Natural selection is a key mechanism of evolution. It is the process by which organisms with traits that are better suited to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This leads to a gradual change in the genetic makeup of a population over time.

Natural selection acts on the variation that exists within a population. This variation arises from mutations and genetic recombination. Organisms with traits that enhance their survival and reproduction are said to have higher fitness.

Over time, natural selection can lead to the adaptation of populations to their environment. It can also lead to the formation of new species through the process of speciation.
