Haploid conten of human DNA is

Options

A. `3.3xx10^(6)bp`
B. `3.3xx10^(9)bp`
C. `4.6xx10^(6)bp`
D. `6.6xx10^(9)bp`

Answer

To determine the haploid content of human DNA, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Chromosome Number**:
- Humans have a total of 46 chromosomes in a diploid (2n) condition. This means there are 23 pairs of chromosomes.

2. **Determine the Haploid Number**:
- The haploid number (n) is half of the diploid number. Therefore, for humans:
\[ n = \frac{46}{2} = 23 \]
- This means there are 23 chromosomes in the haploid set.

3. **Total Base Pairs in Diploid Condition**:
- The total number of base pairs in human DNA in the diploid condition is approximately \(6.6 \times 10^9\) base pairs.

4. **Calculate Base Pairs in Haploid Condition**:
- Since the haploid set contains half the number of chromosomes, it will also contain half the number of base pairs. Thus:
\[ \text{Haploid base pairs} = \frac{6.6 \times 10^9}{2} = 3.3 \times 10^9 \text{ base pairs} \]

5. **Final Answer**:
- Therefore, the haploid content of human DNA is \(3.3 \times 10^9\) base pairs.

### Summary:
- The haploid content of human DNA is \(3.3 \times 10^9\) base pairs.
