JUPEB Top Biology Past Questions.

Published on Jul 29, 2025 • Education

Introduction

Welcome to All CBTs channel!
My name is Ad Bank, and in today’s lesson, we are reviewing 30 JUPEB Biology past questions. These questions are carefully selected from past papers and are highly likely to appear in upcoming JUPEB examinations.

By practicing and understanding these questions, you’ll strengthen your foundation in biology and increase your chances of scoring high in JUPEB.

Let’s get started with the questions and answers.

Question 1: Protozoa and Pseudopodia

Question:
Protozoa that move by pseudopodia belong to which class?

Options:

• A) Ciliophora
• B) Sarcodina
• C) Mastigophora
• D) Apicomplexa

Explanation

Protozoa that use pseudopodia (false feet) for movement belong to the class Sarcodina.

• Ciliophora move using cilia.
• Mastigophora move using flagella.
• Apicomplexa are parasitic protozoa (e.g., Plasmodium).

Correct Answer: B) Sarcodina

Question 2: Bonding Between Complementary Bases

Question:
The bonding between two complementary bases in a nucleotide (e.g., adenine to thymine) is formed by which type of bond?

Options:

• A) Van der Waals force
• B) Covalent bond
• C) Hydrogen bond
• D) Polar force

Explanation

Complementary base pairs in DNA (adenine-thymine and guanine-cytosine) are bonded by hydrogen bonds, allowing the DNA double helix to remain stable but flexible for replication.

Correct Answer: C) Hydrogen bond

Question 3: Basic Unit of Inheritance

Question:
What is the basic unit of inheritance?

Options:

• A) Allele
• B) Locus
• C) Gene
• D) Chromosome

Explanation

The gene is the basic unit of inheritance. It carries instructions for traits passed from parent to offspring, located on chromosomes at specific loci.

Correct Answer: C) Gene

Question 4: Events During Interphase of Mitosis

Question:
Which of the statements describes events during the interphase of mitosis?

Explanation

During interphase, the cell prepares for division by:

• Replicating DNA
• Synthesizing proteins
• Increasing cell size

This phase does not include visible chromosome alignment (metaphase) or separation (anaphase), but it is crucial for successful cell division.
