Final answer:
The yeast protein that acts as a component of an endonuclease for Holliday junction resolution is RuvC, which is different from Rad51 involved in synapsis during meiosis.option d is the answer.
Step-by-step explanation:
The protein in yeast that is a component of an endonuclease responsible for resolving Holliday junctions is RuvC. Holliday junctions are structures that form during the process of homologous recombination, which is a critical aspect of DNA repair and genetic diversity during meiosis in eukaryotic organisms. In bacteria, the RecA protein performs a similar function, and it is highly conserved across different domains of life, including in Archaea as RadA and in Eukaryotes as Rad51.
Rad51, however, is primarily involved in the initiation of synapsis during meiosis rather than resolution of Holliday junctions.The yeast protein that acts as a component of an endonuclease for Holliday junction resolution is RuvC, which is different from Rad51 involved in synapsis during meiosis.
