Section 1: Short Answer (15 marks)
Answer all questions in brief.
Describe the role of ribosomal RNA (rRNA) in protein synthesis.
Answer: rRNA is a component of ribosomes, providing a structural and functional
scaffold for protein synthesis. It helps align mRNA and tRNAs and catalyzes
peptide bond formation.
What is the function of telomerase in DNA replication?
Answer: Telomerase extends the telomeres at the ends of chromosomes, preventing
shortening during replication, which is crucial for maintaining genomic integrity.
Explain the concept of the fluid mosaic model of the plasma membrane.
Answer: The fluid mosaic model describes the plasma membrane as a fluid
combination of lipids, proteins, and carbohydrates. Phospholipids form a bilayer
that allows lateral movement, while proteins embedded in the membrane serve
various functions such as signaling and transport.
Section 2: Multiple Choice (20 marks)
Choose the correct answer.
Which phase of the cell cycle involves the replication of DNA?
