Homologous recombination:

• A. Can occur in prokaryotes and eukaryotes.
• B. Occurs when two similar strands of DNA exchange genetic material.
• C. Only occurs in prokaryotes when the donor DNA has the same sequence as the recipient's DNA.
• D. All of the above are true about homologous recombination.

Answer: (D)

Verified step by step guidance

1. Understand the concept of homologous recombination: It is a process where two similar or identical DNA molecules exchange genetic information. This is a crucial mechanism for genetic diversity and DNA repair.
2. Recognize that homologous recombination occurs in both prokaryotes and eukaryotes. This means that the process is not limited to a specific type of organism, but is a universal mechanism across different life forms.
3. Acknowledge that homologous recombination involves the exchange of genetic material between similar DNA strands. This similarity is essential for the recombination process to occur accurately.
4. In prokaryotes, homologous recombination requires that the donor DNA has a sequence similar to the recipient's DNA. This ensures that the recombination can occur without errors, maintaining genetic stability.
5. Conclude that all the statements provided are true about homologous recombination, as they accurately describe the conditions and occurrences of this genetic process in both prokaryotes and eukaryotes.
