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 features.
- DNA is usually circular, double-stranded.
- DNA lacks histones (except in some archaea).
- Genes are often organized into operons.
Step 2: Eukaryotic genome features.
- DNA is linear and associated with histones.
- Genes contain introns (intervening sequences) that require splicing.
Step 3: Conclusion.
The main distinguishing feature is the presence of intervening sequences (introns) in eukaryotic DNA.
Final Answer: \[ \boxed{\text{Intervening sequences are present in eukaryotic DNA}} \]
