The eukaryotic genome differs from the prokaryotic genome because `:`

Options

A. repetitive sequence are present in eukaryotes
B. the DNA is complexed with histones in prokaryotes
C. genes in the former case are organised into operons
D. the DNA is circular and single stranded in prokaryotes

Answer

### Step-by-Step Text Solution:

1. **Definition of Genomes**:
- The genome refers to the complete set of genetic material present in an organism. It is composed of DNA in both eukaryotes and prokaryotes.

2. **Structure of DNA**:
- In eukaryotes, the DNA is organized into linear chromosomes, while in prokaryotes, the DNA is typically circular and can be either single-stranded or double-stranded.

3. **Presence of Histones**:
- Eukaryotic DNA is associated with histone proteins, which help in packaging the DNA into a compact structure known as chromatin. In contrast, prokaryotic DNA does not have histones.

4. **Gene Organization**:
- Eukaryotic genes are not organized in operons (groups of genes regulated together), which are a characteristic feature of prokaryotic genomes. Instead, eukaryotic genes are often regulated individually.

5. **Repetitive Sequences**:
- Both eukaryotic and prokaryotic genomes can contain repetitive sequences, but their roles and prevalence differ. Repetitive sequences in eukaryotes help in DNA preservation and protection, while their role in prokaryotes is less understood.

6. **Conclusion**:
- The main differences between eukaryotic and prokaryotic genomes include the structure of DNA (linear vs. circular), the presence of histones, the organization of genes (operons vs. individual regulation), and the complexity of the genome.
