Question

Quizplus · Accepted Answer

A Holliday structure is an intermediate in genetic recombination, where two DNA molecules exchange segments or undergo crossover. It forms when two strands from different DNA molecules pair and cross over, resulting in a four-stranded structure that can be resolved through DNA cleavage and strand migration. The other options (B, C, and D) are different types of DNA damage or anomalies that do not involve genetic recombination.
