Which processes ensure the high accuracy of replication? select all that apply?

The processes which ensure high accuracy of replication during DNA replication are PROOFREADING, MISMATCH REPAIR AND NUCLEOTIDE SELECTION.
The cell has multiple mechanisms that it used to ensure that the nucleotide sequences in the DNA molecules are faithfully copied. The proofreading mechanism is used to proofread the nucleotide to ensure that correct sequences are installed in the appropriate places, the mismatch mechanism target mismatched bases while nucleotide selection ensure that the correct nucleotides are used in each stage of the replication process.
