Are any change in the sequence of bases in DNA or RNA that can cause by mutagen or can happen spontaneously in the cell

MUTATION

Explanation:

Mutation is a change or alteration in the genetic sequence of a DNA or RNA (nucleic acid) that are induced by a chemical substance called MUTAGEN or by a spontaneous occurrence. Mutation are of different types depending on how it occurs in the cell. A mutation can be deletion (removal), substitution (replacement), insertion (addition) etc.

Based on this question that states that "any change in the sequence of bases in DNA or RNA that can be caused by mutagen or can happen spontaneously in the cell", the process of MUTATION is being described.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.
