Question

How do eukaryotic genome differ from prokaryotic genomes?

• A. DNA is circular and single stranded in prokaryotes
• B. Intervening sequences are present in eukaryotic DNA
• C. DNA is complexed with histones in prokaryotes
• D. DNA is organised into operons in eukaryotes

Hint:

Remember: Introns (non-coding sequences) are unique to eukaryotic genomes.

Answer 1

The Correct Option is B

Step 1: Prokaryotic genome characteristics.
- Typically circular, double-stranded DNA.
- DNA without histones (some archaea excepted).
- Genes often arranged in operons.
Step 2: Eukaryotic genome characteristics.
- Linear DNA complexed with histones.
- Genes include introns, requiring splicing.
Step 3: Conclusion.
The key difference is the presence of introns in eukaryotic DNA.
Final Answer: \[ \boxed{\text{Intervening sequences are present in eukaryotic DNA}} \]
