You are all referring to mutations, which occur during replication, not transcription and translation.
Three mistakes that can occur in either transcription or translation are:
Incorrect initiation by either the RNA polymerase or the ribosome
Failure to recognize the stop signal by the RNA polymerase or the ribosome
Stalling or slipping, adding or skipping a few codons by either the RNA polymerase or the ribosome.

Thinking a little outside of the box (in eukaryotic cells like ours): DNA Polymerase Alpha skipped/added/inserted the wrong nucleotide, DNA Polymerase Delta's proofreading activity missed the mutation, and DNA Polymerase Epsilon failed to repair the mutation.

Deletion, point mutation, and insertion. Deletion is when a base pair is completely omitted from the sequence. A point mutation is when a wrong nucloetide is placed in the sequence in place of the correct one. Insertion is when a nucleotide is added to the sequence between or after correct ones.

deletion, addition, point mutation (change of one base to another). These all can be harmless or cause a disasterous frameshift mutation or new start/stop codon

Omission, transposition, and addition.
im good like that
