Final answer:
False. MSH is not the eukaryotic homolog of MutS.
Step-by-step explanation:
False. MSH (MutS homolog) is not the eukaryotic homolog of MutS.
MSH is a protein involved in DNA mismatch repair in eukaryotic cells. It recognizes and binds to DNA mismatches and recruits other proteins to repair the mismatched base pairs. MutS, on the other hand, is the protein involved in DNA mismatch repair in prokaryotic cells.
While MSH and MutS have similar functions in DNA mismatch repair, they are not homologous proteins. Homologous proteins are proteins that share a common evolutionary origin. MSH and MutS are not derived from a common ancestor protein, but they have evolved separately to perform similar functions in different types of cells.
