Answer to Question #58339 in Cell Biology for susan Guido

Question #58339
What strategies do cells use to ensure that newly replicated DNA does not contain errors? (more than one answer)

DNA polymerase replaces the newly replicated DNA on any chromosomes on which there are mistakes.

Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotides.

Enzymes repair mistakes in the new DNA double helix after the new double helix separates from the original double helix.

As DNA polymerase synthesizes new DNA, the DNA polymerase finds and corrects misplaced nucleotides

Enzymes remove and resynthesize any misshapen sequences in the DNA prior to replication.

I believe the answer would be these choices - I they correct would their be any others

As DNA polymerase synthesizes new DNA, the DNA polymerase finds and corrects misplaced nucleotide.

Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotide.
