Question

Human genome size is approximately:

• A. 1.3 billion base pairs
• B. 2.3 billion base pairs
• C. 3.3 billion base pairs
• D. 4.3 billion base pairs

Hint:

Human genome: 3.3 billion base pairs.
Approximately 20,000-25,000 genes.
Only about 1.5% of the genome codes for proteins.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The human genome is the total DNA content in a human cell.
Its size is measured in base pairs.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the size of the human genome.

Step 3: Detailed Explanation:
The human genome is approximately 3.3 billion base pairs.
It contains about 20,000-25,000 genes.
The genome size is the total length of DNA in a haploid set.
Thus, the correct size is 3.3 billion base pairs.

Step 4: Final Answer:
The human genome size is approximately 3.3 billion base pairs.
Hence, the correct option is (C).
