The Spo11 enzyme in eukaryotic cells makes:
A)single-stranded cuts in the DNA to initiate replication.
B)double-stranded cuts in the DNA to initiate replication.
C)single-stranded cuts in the DNA to initiate recombination.
D)double-stranded cuts in the DNA to initiate recombination.
E)causes cancer.

Question

Quizplus · Accepted Answer

The Spo11 enzyme is responsible for making double-stranded breaks in the DNA to initiate recombination during meiosis in eukaryotic cells. This allows for the exchange of genetic material between homologous chromosomes, leading to genetic diversity in offspring. Single-stranded cuts would not be sufficient for this process.
