Options

A. 5386 nucleotides and 48502 bp
B. 5928 nucleotides and 49502 bp
C. 9678 nucleotides and 58502 bp
D. 5964 nucleotides and 54502 bp

Answer

To solve the question regarding the length of DNA in bacteriophages φ174 and λ, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Bacteriophages**:
- We are dealing with two specific bacteriophages: φ174 (Phi 174) and λ (Lambda).

2. **Determine the Type of DNA**:
- φ174 is known to have a circular single-stranded DNA genome.
- λ has a linear double-stranded DNA genome.

3. **Find the Length of DNA for φ174**:
- The length of the DNA for bacteriophage φ174 is reported to be 5,386 nucleotides.

4. **Find the Length of DNA for λ**:
- The length of the DNA for bacteriophage λ is reported to be 48,502 base pairs.

5. **Summarize the Information**:
- φ174: 5,386 nucleotides (circular single-stranded DNA)
- λ: 48,502 base pairs (linear double-stranded DNA)

6. **Conclude the Answer**:
- The lengths of DNA for the bacteriophages φ174 and λ are 5,386 nucleotides and 48,502 base pairs, respectively.

### Final Answer:
- The length of DNA for bacteriophage φ174 is 5,386 nucleotides, and for bacteriophage λ is 48,502 base pairs.
