Verified step by step guidance

Understand the concept of genetic recombination, which is the process by which genetic material is exchanged between different molecules of DNA, leading to genetic diversity.

Identify the structures involved in genetic recombination. Key structures include intermediates formed during the exchange of DNA strands.

Recall that a Holliday junction is a cross-shaped structure that forms during the process of homologous recombination, where two double-stranded DNA molecules exchange strands.

Evaluate the other options: Telomerase complexes are involved in extending telomeres, centrioles are involved in cell division, and ribosomes are involved in protein synthesis; none of these participate directly in genetic recombination.

Conclude that the Holliday junction is the correct structure involved in genetic recombination because it physically represents the crossover point between homologous DNA molecules.
