Question

Which of the following is the basic unit of inheritance?

• A. Protein
• B. Chromosome
• C. Gene
• D. Genome

Hint:

Gene = Basic unit of heredity
Chromosome = Collection of genes

Answer 1

The Correct Option is C

Concept:
Inheritance refers to the transmission of traits from parents to offspring. The smallest functional unit responsible for this transmission is called a gene.

Step 1: Understanding Gene

• A gene is a segment of DNA.
• It carries information for a specific trait.
• Responsible for expression of characteristics.

Step 2: Role in inheritance

• Genes are passed from parents to offspring through gametes.
• They determine physical and physiological traits.

Step 3: Evaluating other options
Protein (A)

• Product of gene expression
• Not a unit of inheritance Chromosome (B)

• Structure made of DNA and proteins
• Contains many genes Genome (D)

• Complete set of genetic material
• Not the basic unit Final Conclusion: \[ \boxed{\text{Gene}} \]
