Which MMR protein homologue has not yet been discovered in eukaryotes?

1.	Which MMR protein homologue has not yet been discovered in eukaryotes?(a) Mut L(b) Mut H(c) Mut S(d) Rec JThis question was posed to me during an online exam.I need to ask this question from Repair of DNA Damage: MMR, BER topic in chapter DNA Mutation, DNA Repair, Transposable Elements of Cytogenetics
Answer» Right option is (b) MUT H Explanation: While Mut S homologue (MSH) and Mut L homologue (MLH) has been DISCOVERED in eukaryotes, the Mut H homologue is not found. The nick in the lagging strand is expected to be provided by the unligated okazaki FRAGMENTS.
