Question

The haploid content of human DNA contains:

• A. 3.3 x \(10^9\) bp
• B. 3.3 x \(10^6\) bp
• C. 4.6 x \(10^9\) bp
• D. 4.6 x \(10^6\) bp

Hint:

The human genome is composed of about 3.3 billion base pairs (bp) in its haploid form, and this amount is found in each human gamete (egg or sperm cell).

Answer 1

The Correct Option is A

The human genome contains approximately 3.3 billion base pairs (bp) in a haploid set of chromosomes. This is the amount of genetic material found in a single set of chromosomes in human cells (as opposed to a diploid set, which contains two sets of chromosomes, one from each parent). The correct answer is 3.3 x \(10^9\) bp. Here’s why the other options are incorrect:
- 3.3 x \(10^6\) bp: This value is much smaller and would be more relevant for simpler organisms with smaller genomes.
- 4.6 x \(10^9\) bp: This value is closer to the size of other organisms' genomes, such as some plants, but it is too large for the human genome.
- 4.6 x \(10^6\) bp: This is an even smaller value and incorrect for the human genome. Thus, the correct answer is 3.3 x \(10^9\) bp.
